New version EA2c of install.sh

I’ve just uploaded a new version of the install.sh script. It fixes several minor dependency issues, adds some logging via log4sh, and cleans up the script a bit. Please let me know if you run into any problems installing with this new script.

Note that if you’ve already installed, you do not need to re-run this script (or any future version). The install.sh script is only useful for the initial installation.
