Watch mode: automatically rebuild when there are changes to the file system

[joshtynjala]

Watch source-path, library-path, external-library-path and asconfig.json for changes and rebuild.

Probably using this package: https://www.npmjs.com/package/chokidar

EDIT: Royale's compiler natively supports a --watch compiler option. It is supported with asconfigc's --watch option since asconfigc 1.6.0. See commit a3209fd88793e66e10059de128431e096fb80e34. Other compilers will require a custom solution.
