Fix building syncthing on darwin host
Merge pull request 97 from Zillode/darwin.
Updated syncthing to v0.9.7.
Bumped version to 0.4.9.
Add options to stop sync when not charging or not on wifi (fixes #15).
Start automatically on boot (closes #54).
Extracted SyncthingRunnable into seperate file.
Removed exit button (closes #6).

This has become useless, as the service would be automatically restarted
whenever a network/battery/boot intent is received.
Refactoring of config related functions/constants (moved ConfigXml).
Use Java 1.7.
Remove catch-all statement.
