common event support, more switch support, json support

yet another large refactor (kill me)
add .json output support via '.json' filename
add support for scripts in if statements
add support for finding $gameSwitches for script commands or queries
add support for searching common events
add support for scraping common event triggers for switch usages
fix crash on if statement using switches
fix missing logic for switches when printing results
