Merge pull request #60 from CentralReport/fix-url

Fixed project URLs (http://github.com/CentralReport)
Fixed 'utils.inc.sh' import in the dev tools installer

The import of the "utils.inc.sh" was massing
Removed "Routes" library

Routes requires "setuptools" installed on each host to work. After the security release (PR #44), this library can't work any more.
This is an "emergency" fix. A better solution will be proposed in a next release (custom route object? Use another http framework instead of CherryPy? …)
