How to commit to kruler ?

[Alexander Neundorf]

Hi,

it seems to me that kruler is basically unmaintained, e.g. the patch for bug 
https://bugs.kde.org/show_bug.cgi?id=317436 hasn't been applied since April 
2013.
So, I'd like to fix that now.
How is the procedure for kruler ?
Do I need to post this to Phabricator for review first ? (I don't expect 
anybody to review it, looking at the activity in the bug report)
Or can I simply commit/push ?

Alex
