Fix a bug in waiting for the embedded asset library to be prepared before continuing with the build.
Merge branch 'flash_embedded_assets' into development
Add support for a preloader to the Flash build process.

Matrix had to be changed because of the issue already reported in #143 and #155, or else the compiled preloaded swf will not run without "Error #1014: Class ArrayAccess could not be found." ArrayAccess appears to be optimized out...or is otherwise unavailable. I'm not sure it's being used correctly in Matrix.transformArray anyway, and my change doesn't appear to hurt.

Add width and height options to flambe.yaml and use them to write the flash header during the build process.

Don't set -flash-header when embedding assets, but instead take the header from the asset library. This change facilitates later using -D flash-use-stage to absorb the asset library's timeline so that assets can be stored in a frame after initialization code for the purpose of preloading.
Also a few minor formatting fixes.
Move everything that I can, in the most inflexible way, to 30 fps from 60 fps.

In any of the testing that I've done, 60 fps is inconsistent in the browser, especially if there are other Flash instances running in the background. This causes frequent and noticable framerate drops that are especially visible with fast and smoothly moving objects. I would like to make framerate configurable via flambe.yaml, but it would require a macro to get that value over to the relevant Flambe sources. Such an implementation might call for a more general approach to getting configurable values from flambe.yaml into the code, like what is shown here: http://blog.onthewings.net/2012/09/02/haxe-advanced-conditional-compilation/.
