Title: Fix bootstrap.sh version detection

Running `bootstrap.sh` on a system with appscale 2.0.0 already installed currently results in an error message proclaiming:
> Cannot determine version of AppScale!

This is caused by 2.0.0's a minor version number having only one digit. This patches the regex to support version components with any number of digits.
