Fixes for some project templates

- The Haxe Flash and AIR projects were using swf version 14, while the max. allowed in Haxe 3.1.3 is version 12
- renamed both the `application.xml` in the openfl template and the `project.lime` in the lime template to `project.xml` (consistent with openfl's / lime's own samples / project template)
- updated the lime template for compatibility with the latest haxelib release (2.0.0-alpha)
- fixed missing `$(CSLB)` in the lime template
