Restrict clipboard history file permisions

[aliask]

The default permissions on file creation leaves it open to be read by anyone, which is probably not wanted as this likely contains sensitive info.

Does this make sense? Shouldn't your home dir be r 700 anyway?

[ManuelSchneid3r]

Or rather the entire Albert config dir if we want to make sure that it is safe even if users forgot to set 700

I think I got a bit ahead of myself - of course you're right, everything under ~ and ~/.config should be 700 already.

But I think it's still a worthwhile tweak considering the sorts of things that people copy & paste - SSH keys are still 600 inside ~/.ssh for example.
