Updates installation messages

A lot of the message had inconsistent widths and formatting, from ```=> DONE``` to ```.......done......```. I changed the format so it says ```Installing somepackage...``` and then when it completes, it adds ```done``` without a newline, making the message say this: ```intalling sompackage...done```. I also added the ```-s``` (silent) flag to the curl command so the loading bar doesn't show up. Finally, I added *.swp to the .gitignore file, because those things bug the crap out of me. Thanks for the script, it helps a lot, I just needed something to do while it ran, haha.
