USC cannot install software from PPAs when desired

[Vadim Peretokin]

If I wish to install Ubuntu software that is packaged by the developer and is not available in Ubuntu (or it's latest form, which would be desirable in many cases) - USC does not work as expected. Namely, after adding the PPA to sources as per Launchpad instructions, USC cannot find the software.

A workaround is to use another program, the Update Manager, to run a check on the newly-available software first and then go back to USC to install it. This is fairly unintuitive.
