Updated bash to fix some errors

Setting PS1 without checking to see if $TERM was set meant trying to set
a terminal prompt in incorrect places (eg via scp) and throwing an
error.

Also I was sourcing my fzf config without checking whether or not it
exists.  So it was spitting out errors on hosts that didnt have fzf
installed.
