mimedb: Search all the defaults.list files rather than just the first.

Browse Source 
The first defaults.list file found should not override all the other ones,
it just needs to be searched first.

E.g. For me (cat ~/.local/share/applications/defaults.list) returns
[Default Applications]
text/html=chromium-browser.desktop

So this should be used for text/html mimetypes, but the other defaults.list
files should be searched for other mimetypes.

I had to refactor get_filename so that it can return all the filenames, so
I changed it to append_filenames that appends all the filenames to a list
and provided a wrapper function called get_filename.
