CpConverter - package type calculation should take filters into account

The converter does attempt to (re-)calculate the package type (application, content, mixed) as part of creating the converted packages. However, it doesn't take the targets of the filters into account when determining the type. As such, it is possible that e.g. a package containing a filter targeting apps would end up being classified as being of type content. Furthermore, it when looking into the content, it doesn't take into account if the content is covered by filters - ie., it doesn't really check if the content would be ignored by vault.

Given that it is hard to know what vault will install or not, it might not be possible to fix the second issue - however, it should be possible to at least look at the filters and take their targets into account (as pathes) when (re-)calculating the package type.
