Here is a first attempt:
https://review.typo3.org/#q,I530e9a1fadbbd210c980c62cf2022c38fa81bb56,n,z

The change also contains some smaller cleanups, so I've split it into 4 
patch set to make reviewing easier:

Patch Set 1 only contains minor CGL and documentation tweaks as 
preparation for the upcoming changes.

Patch Set 2 contains a refactoring without real functional change. It 
fixes an issue with duplicates and double slashes though (see inline 
comments of PS2)

Patch Set 3 contains the actual change and introduces the API methods 
setTemplateRootPaths(), setPartialRootPaths() and setLayoutRootPaths()

Patch Set 4 is another non-functional cleanup. It only moves getters & 
setters together to the top of the class for better readability
