* Used Parser::fetchTemplateAndTitle() to get modules and register them in templatelinks. Most of the logic was previously duplicated.
* Changed the configuration and factory functions to allow for the possibility of multiple engines coexisting on the one wiki.
* Made the $parser parameter optional, to improve debugging in the case where a parser is needed but parsing has not started. Removed all $wgParser references.
* Renamed Scripting::getEngine() to getParserEngine() and resetEngine() to resetParserEngine()
* Removed setOptions() and updateOptions(). If you want to change the options, you can always make a new instance.
* Renamed getModule() to fetchModuleFromParser()
* Simplified module constructor parameters and member variable list
* Fixed spelling error langauge -> language
* Renamed a few variables for clarity: $module -> $moduleName, $function -> $functionName
* Renamed getLimitsReport() to getLimitReport() as it is in Parser
* Use an accessor for getting LuaSandboxEngineModule::$contents
* Renamed configuration variable maxCPU to cpuLimit
* Include the full message name as a parameter to ScriptingException. This makes it easier to find messages in the i18n file, and it makes it easier to find invocation points when a translator wants to know how a message is used. Adding the message name as a comment on the same line seems like a waste of space when you can just make it an actual parameter.
* Reduce the number of formal parameters to ScriptingException::__construct(), since there is already too many and we may want to add more things later, such as backtraces with hyperlinks and other such stuff.
* Include the code location as $2 unconditionally so that there is less chance of getting the parameters wrong
* Shortened some message names. Wrote English text for messages without it.
* Removed ScriptingEngineBase::load(), inappropriate interface specification, only used by child classes and more properly defined by them
* Fixed inappropriate use of final
* Fixed case of a class constant to conform with MediaWiki conventions
* Use a factory function interface for module creation instead of a class name accessor
* Don't pass unnecessary $engine parameter to ScriptingFunctionBase::__construct(). Pass parent object as the first parameter per convention.
* Fixed unnecessary reference parameter in doRunHook()
* Have LuaSandboxEngineFunction::call() return the first result or null, per the base class documentation, instead of imploding.
* Use strval() to avoid a warning in case call() returns an array or object
* Improved some comments
* In importModule(), don't catch exceptions since that luasandbox bug is fixed now
* Use the chunkName parameter to loadString to get more informative error messages
