.midi files cannot be opened from the sidebar

[Monospace-V]

Bug Summary

From the import dialogue, MIDI based files with extensions ".mid," ".midi," and ".rmi" can be opened. But from the sidebar, ".mid" files can be opened but ".midi" files cannot. I don't know about .rmi, though...

Steps to reproduce

1. Download a file with extension .midi instead of .mid, like https://drive.google.com/file/d/1NqxQmdP63N711_NKFal-2lAWt7Vu39XD/view?usp=sharing
2. Navigate to it from sidebar and attempt to import it into the project

Expected behavior

MIDI file is imported

Actual behavior

MIDI file is unusable from sidebar.

@Monospace-V I think it's enough to change this

lmms/src/gui/FileBrowser.cpp

Line 1246 in ae4d1b5

else if( ext == "mid" )

to

else if( ext == "mid" || ext == "midi" || ext == "rmi" )
