Engine/GCTScript: Refactor script manager (#580)

Browse Source 
* refactor script manager

* remove singleton GCTScriptConfig
* create constant for ".gct" extension
* move GctScriptManager into vm package
* reduce script manager global dependencies
* use manager struct to store runtime override values
* enable/disable scripting subsystem now doesn't store the setting in
config (aligned with other subsystems)
* setting max VMs via start option doesn't change config

* instantiate scriptmanager as part of creating a new Engine

    * script manager config is now set during instantiation
    * run script manager when enabled in conf or explicitly enabled
    * use the Started() method to check if script manager is running

* in tests set script manager as running

* script manager adjustments

* create manager before attempting overrides
* check for nil config when creating script manager

* fix script manager waitgroup counter increased too late

* move autoload() function to autoload.go
* add tests to script manager
