dragonworx, a user from the FlashDevelop message board took the time to write an SWC compilation plug-in for FlashDevelop.

I personally have not yet put it to use as i am waiting until solutions are implemented in FlashDevelop and i can build all my crap in one go. Until then i still go for my .bat approach.
