Added new stock to helpers.inc: LoadMaps()

Adjusted all plugins that use LoadMaps()
Nextmap no longer worries about mapcyclefile until the map changes
RTV/MC/RC use OnConfigsExecuted() instead of OnMapStart() now
RTV/MC/RC will no longer "permanently" exclude the current map being played when the map file is loaded.
