Removed Ubuntu 11.10 and added 13.10 as supported versions.

Writing this from a 13.10 machine I just built code on, so we know it works.
11.10 is EOL as of May of last year - we can expect it to break on new machines.
Setup script automatically finds Ubuntu version
Made the 64-bit check automatic while I was at it
Create list of packages to install & hold @ 12.04 versions
Tool links on 13.10 with Lizzie's flags.
Added libboost-python to packages held back to 12.04 versions
make cross and straight both work after including unistd.h in LogModule
apt-get with -y to remove some interactivity
Install old packages before new packages, keep back Python
Merge remote-tracking branch 'origin/ubuntu13.10' into 14.04
Swapped setup script to use wget instead of rsync - no password required
No real reason to have the .bashrc line be optional
Don't try to hold back Python
Bash doesn't like my /n's
Merge branch '14.04' of https://github.com/bjacobel/nbites into 14.04
Merge pull request #650 from joshimhoff/14.04
