Make texts more consistent

[felagund]

Hello, I am now translating a new version into Czech and apparently Weblate has some new tool to spot inconsistencies in translations (different strings having the same translations and vice versa). That also shows inconsistencies in the original. What I found:

1) https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L2589 "Mail" should be "E-mail (as on other lines like 870 an d942)

2) (also writing e-mail an email should be unified to either, I suggest e-mail, it uses both all over he place it seems to me)

3) https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L3022 should be "Regenerate and e-mail a password" as on https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L2966

4) On https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L1766 and https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L752 "Credential" should be "Credentials" - if I am not mistaken, it both pertains to generating credentials for all voters, so plural.

5) https://github.com/glondu/belenios/blob/master/src/web/clients/admin/elections.ml#L1306 and https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L2299 should probably be unifie to "and save them in a secure location." - it is used elsewhere more than just plain "securely"

also possible to alter at: https://github.com/glondu/belenios/blob/master/src/web/common/mails_admin.ml#L241 https://github.com/glondu/belenios/blob/master/src/web/common/mails_admin.ml#L157 https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L2145 https://github.com/glondu/belenios/blob/master/src/web/server/common/site_admin.ml#L804

6)https://github.com/glondu/belenios/blob/master/src/web/clients/admin/admin.ml#L177 and https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L220 should unify, either on (untitled) or (no title)

7) https://github.com/glondu/belenios/blob/master/src/web/clients/admin/trustees.ml#L147 should be "Add a trustee" as in https://github.com/glondu/belenios/blob/master/src/web/clients/admin/trustees.ml#L196

8) https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L2944 and https://github.com/glondu/belenios/blob/master/src/web/clients/admin/elections.ml#L466 shouldbe unified to "Delete the election"

9) There is a typo here: https://github.com/glondu/belenios/blob/master/src/web/clients/admin/elections.ml#L1055 (space before colon) and https://github.com/glondu/belenios/blob/master/src/web/clients/admin/trustees.ml#L350 (space before question mark)

10) https://github.com/glondu/belenios/blob/master/src/web/clients/admin/account.ml#L79 should be "Log out" like in https://github.com/glondu/belenios/blob/master/src/web/clients/admin/elections.ml#L1055

11) https://github.com/glondu/belenios/blob/master/src/web/clients/admin/questions.ml#L436 should be "Condorcet-Schulze method" as in https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_voter.ml#L1061

12) https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L1891 should be unified with "List of voters:" https://github.com/glondu/belenios/blob/master/src/web/clients/admin/elections.ml#L817

Thank you for your valuable suggestions!

@glondu Thank you, weblate complains a lot less now.

There are two things:

1) "Mail" here: https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L1152 shoulbe "E-mail".

2) "List of voters" in these: https://github.com/glondu/belenios/blob/master/src/web/clients/admin/elections.ml#L817 https://github.com/glondu/belenios/blob/master/src/web/clients/admin/elections.ml#L818 https://github.com/glondu/belenios/blob/master/src/web/server/common/pages_admin.ml#L1816

should be made into "voter list" (it is used more elsewhere).
