jquery.mentionsInput (dtime flavor)

This is a modified version of: http://podio.github.com/jquery-mentions-input

with the following changes:

• Adds onCaret support (enabled by default)

• The text inside the textarea will be used and properly initialized if the textarea already has a value

• Multiple trigger characters are allowed - set triggerChar to an array. We use ['@','#'] so that tag mentions are treated the same way as username mentions. It is your job to filter by trigger character in the onDataRequest function (which takes a fourth argument trigger).

• The trigger character is included in the value of the mention so you can still see it. This is useful for distinguishing between multiple trigger chars. This only happens if a trigger is set on the mention, or a default trigger char is set.

• Formatting now is of the form:

  [@username](user:user_id) instead of @[username](user:user_id)
