Made .irbrc simpler.
I made this .irbrc on day one of DBC, and haven't tested it much since then
Your code review of my bash profile made me wonder what else was happening
for no reason.  I have removed the lines of code there that were doing
(as far as a i can see from testing) nothing worthwhile.
Added more comments for explination
Changed spelling error and standardised capitalisation for comments
Also removed gem comments
Updated awesome print line comment for clarity
Merge pull request #4 from Devbootcamp/less-complex-fancy-irb
