audio import is case sensitive for file types (wav vs. WAV)

I’ve only tested this on OS X, problem probably exists on other platforms as well. 2.0.2 version (which is gorgeous btw)

When browsing for/importing existing audio files, the file dialogue only display audio files with lower case extensions (e.g. ".wav"). Files with upper case extensions (".WAV ") are not visible.

Renaming them and reloading the directory browser makes them show up, which leads to the assumption it’s fixed by simply making your file searches case case insensitive.
