Added convenience script for easily loading your bashrc changes.
Back-up current bashrc first in gobash.
Removed source line in gobash since, apparently, it does not work that way.
Added stats and brc function in bashrc.

stats will give you your most typed bash commands. You can call with an optional
parameter to specify how many entries would you like to see.

brc simply sources ~/.bashrc (in compensation with its removal in gobash; see
846fc2f1cc95147e044eca7939e800bd503df5a9).
