Changed Readme

Cleaned up readme file. Switched screenshots back around because the
default logo is not colored. Removed “Credits” (was getting a bit out
of hand, plus you can see who it was forked from and who contributed
anyway).
Install Script Cleanup

Removed options for installing into /bin. Removed the orig variable
(not needed because not changing directories). Added prompt after
action is complete.
Updated To-Do list

Package manager should be detected automaticly. Smarter install script
and look into installation via package manager.
Code cleanup

Was getting a bit messy so I’ve added subheadings so relevant code can
go under each heading. Changed $ram back to $mem.
