no problem. I guess the keywords all/theme should be in.

In genereal a second call only adds the missing part. First call without 
adapter, second with adapter will only add the adapter.

there is imho no reason for. Remember that this is used for modules, who 
should call it a second time? Only wrong code of dev can cause this. It 
would be different if it's for FE.

At the moment we don't have the compressed version. I know from own 
expieriences that it's not easy to compress extJS - the minifier won't work.
Language will not be loaded, it's set in Code. ExtJS takes care of 
loading the language, it's done with something like this:
Ext.urlEncode({"lang":language,"charset":charset});

Maybe a good idea to include this beside the cleargif.
