key bind for list of delete marks (#27)

* key bind for list of delete marks

https://github.com/zenyd/mpv-scripts/issues/14

* make show list a toggle so we don't spam the terminal

* put showListTimer:resume() in condition

* undelete all and globalize timer

if timer is local showList() can't reference it

* add new keybinds

* add space to help wrapping

* better matching

 As the name suggests this is a small script for deleting files played through mpv. You can mark a file to be deleted and can unmark it if desired. Once quitting mpv, the script starts the deletion process. This is platform-agnostic so should work everywhere.
 
 `ctrl + DEL`: mark/unmark file to be deleted
+`alt + DEL`: show the list of files marked for deletion
+`ctrl + shift + DEL`: clear the list of marks
