Commented alterForWhisper

It didn't even return anything...
Added a description of sleepychat for SEO

It reads "Welcome! This is Sleepychat, a website for hypnotists,
subjects, and people who just want to learn! All kinds of hypnosis are
acceptable here, from theraputic to recreational to erotic. The only
rule here is that you should be kind :) "
Altered incorrect emote regex.

The emote regex was altered to allow for sanitized characters next to parentheses without mistakenly adding a ";" character and bolding it, but the fixed regex was written incorrectly. This commit fixes that.
Fixed "&" sanitation.

With the added sanitation of ";", the & sanitation interfered with the html codes for the characters. This fixes that, such that "&" will match, but any character code, consisting of "&#" does not match.
Added bolding

Also simplified italics
Added more formatting options

__underline__, --strikethrough--, `monospace`, ``serif``
Changed font to "Roboto"

It is superior to everything else. Note, page load tome should increase
by 40-60 ms. I also fixed a comment
Require space before emoticon,

Or the emoticon could be at the start
Added/fixed emoticons
Made information slightly bigger than messages
Merge pull request #16 from scottbutcher/master

Just some minor changes :)
