Initial release

Catch errors when unable to fetch wiki pages/images to prevent crash.

Fixes #1, albeit in a not-very-graceful way (pages are not saved, left a little
blank, etc).

Initial debug build

For testing purposes only. Signed by a debug key. In the future, will be released on F-Droid and signed by F-Droid, at which point you would need to uninstall this version.
