[IMPORTANT] Change in branch handling in emerge

[Patrick Spendrin]

Hi everybody,

because we decided to base the 4.10 branch on master rather than on the
4.9 branch, I also decided to change the policy on forward porting commits:

For kde-4.8 and kde-4.9 commits must be cherry-picked.
For kde-4.10 and all upcoming releases, commits must go into the latest
branch they apply to, and then must be merged into all branches( you
need this fix in).

I hope this is clear and suits your needs,

more information on KDE 4.10 soon.

regards,
Patrick
