Ignore assembly from coverage results

[pver]

Sometimes it's handy to exclude certain assemblies from the coverage results. For instance, the assemblies containing unit tests, or specific third party assemblies.

As a first step, we could provide a settings file (solution specific) that keeps a list of these ignored assemblies.

Later on, we could integrate the option to add or remove assemblies from this 'ignore list' through the testresults UI

I am working on a settings screen (basic) that we can extend to manage this - I am still learning how all this hangs together - but I've stopped crashing :)
