vPav.properties discovery does not work

[sdibernardo]

As of now vPAV scans for properties with the following line of code:
input = this.getClass().getClassLoader().getResourceAsStream("vPav.properties");

This leads to searching inside vPAV's Jar for the specified properties. Instead, this file should be looked for inside the project using vPAV and also neglect upper- and lowercase characters.
