Added "resource" path option to the compiler tasks (#1399)
Factored out the adding of files from the (re)source folders to the compile list (#1399)
Moved arguments to the the JS compiler task before the list of modules and files because the Ceylon tools don't support options after arguments anymore
XXX
For filterModules() we now look both in the sources fodlers as well as the resource folders (#1399)
Silly me, the JS compiler doesn't support --resource yet of course (#1399)
