updated chokidar
using chokidar without polling
ignoring errors when widget has been deleted
loading scripts from widgets should work now
no more version checking (behaviour is the same on Mavericks it seems)
Merge branch 'master' into better-file-watcher

Also installed newest chokidar to resolve conflict.

Conflicts:
	server/node_modules/chokidar/node_modules/fsevents/.npmignore
Merge branch 'master' into better-file-watcher
not browserifying chokidar
