LHCb specific page is removed

I hope this time is okay. I modified the Compiler.py(Sencha will remove the first line from the compiled code). I added the missing "import"s to the JS files. In order to reduce the size of the compiled file it is better to not use * for example: Ext.grid.*. It is not the case now, but  maybe it is not worst to modify the "import". 
import == requires in JS
