Updating Spanish translation according to latest changes.
Moved README and LICENSE

These two files are better off in the root folder. Also testing GitHub
for Windows...
I would like to include the updater in the next release, but translators need to have some time doing their work. So here are the texts for the time being.
Updating  (Again) Spanish translation according to latest changes.
Fix: It was not possible to compile when SDL mixer was not present on the system.
Change: Disallow FFMPEG if Sound has been turned off.
Change: The hover text in the customise dialog is now the long version for both label and button. The designated button tooltip didn't really add anything in my opinion, and if you don't understand that the label has more info you are at a loss. I hope you don't mind Mark. :-)
Added: Automatic update check given that LuaSocket is available.
Added: Some more checks for possibly corrupt files in the Theme Hospital folder. This way I hope we don't get that many bug reports and comments on facebook that are only due to bad original files. Disabled Easy and Hard if those level files are not present.
Updating Spanish translation according to latest changes.
Ugly commit that 
1. Adds the MIT license to the LevelEdit source files.
2. Changes tabs into spaces to use the same standard as our C++ files.
3. Moved the files into a package.

Even though it might look like it there has been no changes to the actual code.
Fixed the the color erroneously introduced in r2460.
Merge branch 'master' into sdl2
