Change Order of Compilation Process, Allow Duplicate Processes

[aarmastah]

Is your feature request related to a problem? Please describe. I store my custom assets in a tf_dev folder in the base Team Fortress 2 folder to isolate them from the main game. When trying to compile a map via CompilePal, it is not currently possible to pack the content before building cubemaps and generate a nav mesh (then packing again), leading to errors.

Describe the solution you'd like Allow reordering the list of compilation processes and allow multiple of the same process (ex. 2 packs)

Describe alternatives you've considered It's possible for me to compile the map normally and do cubemaps and nav generation manually before packing again, but it'd be easier if it were all automated in CompilePal. Currently that is not possible without running a compile twice.
