Modules Config "BasePath"

[enusbaum]

The goal with this PR is that we can specify one BasePath in a Module Configuration File. In the near future, this will make packaging a "MBBSEmu Game Pack" easier to distribute as every module can be relatively pathed off a root folder with a single configuration.

Additionally, it should make managing a Modules Config JSON file with multiple modules easier to manage if all the modules share the same relative path.

• Add BasePath Option to Module Configuration JSON
• Create new JSON ModuleConfiguration Converter that loads Modules from the JSON and applies Base Path to each deserialized Module
• ModuleConfiguration will now apply BasePath to a modules specified path if it is set, and the Module path specified isnt a Root path

Oh -- I guess I could write some Unit Tests for this as well :)
