Possible new interface

A different design of the UI. Just different, not necessarily better.
Updated copyright
Added a different login screen

Need to add a switcher between the different screens, though.
Ignores useless files.
Removed stupid ds_store file
Cleaned up syntax and flow

Removed a few capitals that weren't supposed to be there, clarified a few terms. Nothing exciting.
filename now points to the latest minecraft jar filename

Since mojang just begun to rename their minecraft jar files with the version number, this just makes it easier to the end user if they are running the most recent version of minecraft.
Improved readibility

Added some tabs. I must say, I do like my tabs and spaces.
