Categories updated to v2.18

Right after BossPrefs update, Categories updated to v2.18. Here is a changelog from 2.16 to 2.18:

v2.18

• Settings App: Fixed issue where app kept crashing on load for a few people(most these people had adblockersin their etc/hosts).

v2.17

• Settings App: Replaced Default.png.
• Settings App: Added some new icons by Andreas Ficher.
• Settings App: Added admob into settings app GUI (note, no plans to have any ads in launcher).

v2.16

• Launcher: Removed dependency on springbridge and am lanching apps the old way thanks to Saurik who figured out that it just needed to be signed with the correct entitlements.
• Settings App: Did not rev, still at 2.15.
