Tweaks (Event App)

-Fixed a bug in multi-byte string wrappers which was causing the
encoding to not be properly set to UTF-8, thereby causing multi-byte
characters to be handled incorrectly, causing a cascade effect where
names with non-ASCII characters in the delegates list would simply be
deleted.
-Various style tweaks.
-Fixed link sorting issues.
-Fixed link visibility issues in the personal schedule.
-Removed check for paid delegates from the delegates list and login
system
-Fixed handling of various values from MySQL.
