Issue #1774 - http://play.lighthouseapp.com/projects/57987/tickets/1774-dprecompiledtrue-not-using-precompiled-templates fixed.

Precompiled templates and "routes" files from application and dependent modules used when Play! started with "-Dprecompiled=true" switch.
All template sources ("app/views"and "modules/*/app/views" can be removed). Application "conf/routes" file cannot be removed because Python scripts check if it's present. "modules/*/conf/routes" files can be removed.
For every file if there is no precompiled version available, source version will be used (id present).
