Get amxmlc and mxmlc using javanailgun and drop flex 3 support
Twas released
Add a flexserver macro.

Reference the proper repository for asimports
Extracted the checking for Flex into a checkflex macro which can be called by
build scripts that want to allow optional compilation of their ActionScript
code.

Made {$env.FLEX_HOME} actually work, since one has to first tell Ant "please
load the environment into the prefix 'env.'" before they can use it. Yay!
Add the scm location to the pom to be a little friendlier to future users
Add some air packaging macros
flex sdk default 4.1 -> 4.6
bump maven version to 1.6
Allow the "tsa" (timestamp server) argument to be overridden

The timestamp server frequently to respond, which makes packaging impossible
unless you tell adt not to use a timestamp by passing -tsa=none
Stop relying on a phantom snapshot of aspirin

As far as I can tell, this only works if you happen to have that snapshot on
your hard drive. I don't see it in any of the usual places.
