Add displayGameName() and lootGameName() to plugin-base (#141)

* Add `displayGameName()` and `lootGameName()` to plugin-base

# Modifications
- Add `lootGameName()` which gives the plugin a tad bit more control over LOOT cli args
- Add `displayGameName()` which will be used separate display-specific calls & more integral calls to `gameName()`, will also pave way for deeper plugin localization

* clang-format
