Small bugfixes

Mostly the same as last release, updated version in manifest and small bugfix applied.

Update with a newer way of changing the mac address

After having invested much of my time into investigating how android handles mac addresses, working out what is going wrong and trying to think of ways to get around them, I bring you this.

This new method should work on more devices, as long as you have a /system that can be remounted and written to.

Initial Release

Have compiled this app into an apk for easy sideloading. I wrote it reasonably quickly so it may have bugs in. However, it seems functional for myself for day-to-day usage...
