[FEATURE REQUEST] More appearance customization

[ruro]

Currently, each file is displayed as a fairly large icon (or preview if available) alongside the full path.

Here are a few suggestions, that in my opinion would allow for better customization:

1. --no-thumb don't show preview thumbnails, use file icons for all files
2. --icon-size to go along with --thumb-size
3. --font-size already requested in Allow to specify a font size #30
4. --verbatim-arguments show the file names exactly how they were passed on the CLI instead of normalizing to an absolute path (so dragon-drop foo will show foo, dragon-drop ../dir/foo will show ../dir/foo, etc)

Here's a mock up of dragon-drop --no-thumb --font-size 28 --verbatim-arguments bar baz download.jpeg foo:
