Search is broken due to not url-decoding

[Jon007]

Search is broken with any character that is url encoded, including spaces. This is easy to test and confirm by turning off next template packs.

For example, a search for the user "Jonathan Moore":

• turn off Next Template packs, search returns result (assuming you have the named user) and with "Jonathan Moore" visible in the search box
• with Next Template packs, no members are found, and on screen refresh the search box has changed to "Jonathan+Moore" and there is no user of that name.

We can put the url generated by Next Template Packs /members/?members_search=Jonathan+Moore&dir_members_search_submit= back into the legacy and again it works fine, the legacy understands that "Jonathan+Moore" should be decode to "Jonathan Moore" for the search.

This applies to other characters in the URL for example: /members/?members_search=superman%2Fwoman will correctly search users for the string "superman/woman", but the Next Template Packs will not.

Thanks for the detailed report though, it'll be looked into.
