fixed 'no matches found'
can probably skip pgrep and use xdotool search
switched to xdotool search, but output is a str with the process IDs that need to be seperate
splitlines() to make list of pid's
added docstring, found option to only get visible windows, maybe dont need to loop ids
added docstring to activate_window
added --onlyvisible, and renamed argument for activate_window, kept activate_window loop because more than one instance might be available to activate
activate_window.py complete
activate_window.py docs updated
updated .gitignore
