Verify that source IP is valid for server requests

Currently, server authentication for updating the ladder and for
uploading replays is done by comparing the hash of the token provided
by the server to the hash on record. This commit adds a second layer
of authentication by also verifying that the request actually
originates from the Pokemon Showdown server in question.

For now, I have also maintained the server token check as a form of
two-factor authentication.
Adding highlighting words

Added highlighting words:
Users may now use the new highlight commands:
-Use /highlight add, word to add a highlighting word.
You might add several words separated with commands.
-In a likewise fashion, /highlight delete, word deletes words.
-Using /highlight delete with no words will delete all.
-/highlight show or list will show all current highlight words.
-By default no word is added to highlights.
-Words are escaped

Add `rows` attribute to teambuilder <textarea>s

Firefox renders the height of a <textarea> based on the `rows`
attribute, which was not previously specified, causing the <textarea>
in the teambuilder to be very short. This commit specifies a
(somewhat arbitrary) `rows` attribute so that the <textarea> has
some more height.
