Tons of formatting changes by Jon Tai.

Didn't merge changes to imap_search.php, as I wanted to take a
closer look at it.

Jon Tai said:
I cleaned up the four imap_*.php files - fixed comments so they use the
/* */ style, fixed spacings, added { } around logic blocks that didn't
have them, etc.

I also hacked sqimap_find_email() in imap_general.php to support strings
in the form of "lehresma@css.tayloru.edu (Luke Ehresman)".
