Migitates/fixes #314
Introduce SyncPrepare state

SyncPrepare is when the folder class prepares the actual syncing,
i.e. does treewalks and runs the reconceiler in case of mirall. The actual
SyncRunning state will only be entered if there is actually anything to
sync.

Fixes #289
Add more debug in case inotify fails

We should probably make this at least a visible error, because it's a
limitation set by the kernel/the distro and we would require root
permissions to adjust the value.

Right now all that happens is that syncing is not immediate, but only
run every 30 secs (due to server polling).
Fix crash when pausing mirall.
Set csync config dir in mirall properly

Otherwise canceling the sync cannot remove the lock file
