Thanks for the many reviews! Unfortunately I had to push a new patch set 
to ensure that '@controller' is replaced correctly. I also added 8 more 
tests covering all kinds of (theoretical) scenarios.

Please vote again so we can merge and back port this asap:

Regarding the backport we should agree on how we want to define the 
conventions. For example if the ExtensionBuilder code templates[1] 
should be adjusted to use "templateRootPaths" etc.

I'd propose following conventions:
Keep defaults but suggest (= document) the following scenarios:

1. Change 3rd party extension templates (as before):

# loads all templates of "original_extension" from 
Resources/Private/Templates of "my_extension"
tx_originalextension {
	templateRootPath = EXT:myextension/Resources/Private/Templates
}


2. Change a subset of the 3rd party extension templates:

# loads all templates of "original_extension" from 
Resources/Private/Templates of "my_extension" or "original_extension" if 
it wasn't found
tx_originalextension {
	templateRootPaths {
		tx_myextension = EXT:myextension/Resources/Private/Templates
		tx_originalextension = EXT:originalextension/Resources/Private/Templates
	}
}

(with proper English and possibly better examples).
