Implement banning of users

[mattrobineau]

There are going to be 2 types of bans, soft and hard bans.

Banned users behaviour

• ~A banned user cannot post a comment or story~
• ~Banned users cannot invite other users~
• ~Stories by banned users remain on the board (overridden by flag status)~
• ~Comments by banned users remain on board (overridden by flag status)~
• ~User profile will show if a user is banned~ (3811e890e3d3a38be3f34343be33295ae34e8745)
• ~Banned users cannot upvote~ (a57f936db67cf17a4acf942093330df2256461b7)

Soft bans

• ~A user can still login~
• ~The ban has an expiry date~ determined by mod/admin at time of banning
• ~Email is sent to user stating ban and reason~ (#37)
• ~User profile shows ban, ban reason and expiry date~ Users cannot login when banned. No reason to add this

Hard bans

• ~Never expires~ determined by a mod/admin at time of banning
• ~User cannot login~
• ~Email sent to user stating ban and reason~ (#37)
• ~Stories and comments by user has username replaced for "[banned]" (or something similar)~ (a57f936db67cf17a4acf942093330df2256461b7)

Ban order

• ~Admins cannot be banned~
• ~Only admins can ban moderators~
• ~Admins and moderators can ban users~

Commit 983bd2a8507e04c7445c87d434d65f5276ef29d4

• Added validations for banned users when Create/Update/Delete of comments
• Added validations for banned users when Create of stories
• Added validations for banning a user (Moderator cannot ban admin or moderators)

[mattrobineau]

An admin/mod who bans a user will determine whether it is a hard ban or soft ban by setting or not setting an expiry date.

All code requiring different behaviour between a hard ban and soft ban will be determined by the ExpiryDate property (null == hard ban)

[mattrobineau]

After further review, a user who is soft banned cannot login. This is the same behaviour for all bans now.
