Adding desktop file entry for QOL

[weiseguy1]

Updated the original makeDesktop patch

@sevz17 I'm wondering if it couldn't be merged since it doesn't increase SLOC in dwl.c nor any header files and is just a few lines in Makefile. Also it just makes things easier if someone uses login manager since it's automatically discoverable. It doesn't alter the behaviour of dwl but it's just QOL improvement for people that need it.

Well, dwm doesn't include it so neither do we, but meh, let's do it.

Also do note that just like sway we don't support login managers (I know, it's not mentioned anywhere, I want add it and more documentation but I haven't had time)

Not gonna lie, this is pretty cool considering this is my first pull request to a major project!

One last thing to do. Squash the commits into one and that's it from my perspective.

Give that commit sensible name like Add desktop entry file or something similar. Also change the PR name since it's meaning has changed.
