Enable swf.instance.MovieClip flatten, filters, and more Dynamic TextField properties

Hi, I made some additions and minor modifications. flatten seems to be working ok so I took the liberty of exposing it. 
I really don't know if what I did was done in the best way to do it, but I tried to code it in the same way that I found the rest of the code. Any suggestions would be welcome.

Thanks!

More in detail:  

MovieClip:
- Remove comments to flatten and add a stop() before end of function
- Set width, height, multiline, wordwrap, autosize and border to
createDynamicText
- placeObject function now checks for filters and adds to displayObject
when found
Bitmap:
- will look for alternatives for JPEG parsing
