fixing jsmessages to allow some parsing; reducing the amount of VET mess...

...ages sent to jsmessages

This adds wikitext to html parsing for all messages sent to JSMessage, so we'll now be able to have messages like this used in $.msg():

Some '''bold''' and ''italic'' text that's a [[link]]

Since it's impossible to know which messages will need parsing and which won't, I'm using parse() for all of them.  

I also noticed that there were 89 extra VET messages being loaded unnecessarily with JSMessages on every page.  Now we're only loading the necessary 3.
