[RFC|Merged] Enable template inheritance by default

[Arty]

Two patch will be needed:

• 3.x: compatible with [RFC] Merge style components
• 3.0.x: for template.cfg

No need to make it compatible with that RFC. That RFC will have to be coded with assumption that this RFC will merged.

Its a chain of RFCs that require to be implemented in certain order, that order is one way or things will get very messy.

I did pull request for develop-olympus instead of develop because this can be added to 3.0 without being a new feature. It doesn't require new language variables, there are no database changes and it doesn't affect existing 3.0 styles.

This RFC has been merged to develop-olympus and develop.

Title needs changing to reflect the merge, and it should probably be moved to the 3.1 RFC forum or 3.0 discussion.

Moved to 3.1 and added to 3.1 list of RFCs.
