String freeze exception for Amarok (Extragear)

[Matěj Laitl]

Hi translators,
I'd like to request a string freeze exception (2 new strings) for Amarok. We 
changed mouse behaviour in 2.8 Beta, but it turned out the change was too 
drastic for some users, so we decided to introduce an option.

The patch is at https://git.reviewboard.kde.org/r/111635/diff/#index_header

Amarok 2.8 won't be released sooner than in a week (we're not part of KDE SC), 
so there should be some time to translate these.

Thanks,
	Matěj
