Suggesting several changes

1. A restructure is recommended (but not essential). Just to seperate the whole plugin from everything else.

2. The package.xml needs an update. The declaration of the used application (wbb) is missing. Furthermore, the author of this plugin is "Tapatalk inc". "Tapatalk" is the product name.

3. It's a good idea to create a LICENSE file, so people don't have to search for it in the depths.

4. Since the github version of this "extension" is a proper WoltLab Community Framework package, the Installation.txt is obsolete. Instead, a README.md makes more sense, including a short instruction, how to set-up the plugin.
