Closes #21 - File loading in order
* Reworked LoadFiles to smaller methods for readability (also re #10) and structure
* Now determine expected load return before loading then load all "expected GameSystem" before "expected Race"
* Make "can load as race/game system/army" methods public in interface
Re #22 - Get errored file loading
* Created FileLoadFailure class and made LoadFiles return a list of them
Also
* Some code cleanup
* Change to DictionaryUtils calls
