fix: wrong application/mp4 mime type from extension

[Tornhoof]

application/mp4 is put onto an ignore list.
closes #160

[zone117x]

This change should be made to the data source at https://github.com/jshttp/mime-db#mime-db right?

[Tornhoof]

I don't think so, the JS lib (as far as I can see in the Readme) does mimetype -> file extension.
The problem here is file extension -> mime type

please split our the formating changes to a seperate pr

[Tornhoof]

done, the whole Witespace fixes were an attempt to reduce the WS diffs in github, so i recommend reviewing it without whitespace

can we do the whitespace change first in a separate pr, so future pr's benefit from less whitespace changes?

[Tornhoof]

The problem with T4 templates is, that the generation is heavily dependent on your VS configuration, just like in the good old days. All my attempts to recreate a setup without whitespace changes failed, it might be possible with things like .editorconfig files, but I have never used them.
