Flex 4: Two-way Bindings and Other Improvements

Carol Frampton added inline support for two-way binding. Using the syntax of "@{expr}", you can now more simply support two-way binding.

Gaurav Jain added support for ASDoc comments in MXML files. "For adding comments at the class level or to properties defined inside mxml use the syntax <!--- comment (notice 3 dashes at the start) -->"
