SourceCode migrated to Github & Bug Fixes

I've migrated the source code of this project to github (https://github.com/maxheadroom/sortimages-gui) as I'm more active over there.

I've also updated the project with a new version of Drew Nokes metadata-extractor and a newer version of the MySQL connector.

I fixed a bug where images would not be inserted into the Database of the image contains not EXIF tags with the image dimension.

Next feature will be a SQLite implementation to make it independent of MySQL.
