Logsearch login failing when password contains percent sign

[Chad Woodhead <ch...@gmail.com>]

I am running logsearch 0.5.0 and I have noticed I am unable to log in to
LogSearch UI when my password contains a "%" symbol. Other users who do not
have a "%" in their password can login just fine. Here is the stacktrace:
