Standardise command line option parsing (#6036)

* Separates long & short options for parsing

* Adds parsing for short options + doc rewrites

* Fixes undefined constant in check.translation

* Standardises CL option parsing

* Refactors option parsing

* Renames getLongOptions -> getOptions

* Removes unused code

* Converges on string typing for options

* Updates docs & help files

* Updates array syntax array( ) -> [ ]
