Removed all extraneous copies by adding the class 'InterfaceReg' which will construct a new interface, and link it to the engine's static register. The Source Engine macro 'EXPOSE_INTERFACE_FN' will help utilizing this. The game module from the plugin is not obtained through the process environment block, so the executable is no longer sensitive to names.
Moved construction logic to separate method, and call that from constructor instead. When willing to change the entire context on the same object, you can now just call 'InitFromXXXX()'. Previously, a whole new object would be generated and copied into ours, and then deleted again.
*Use unordered_map to get mpdule sections instead, as this is more performant than comparing strings.
* Removed 'm_SectionName' field from ModuleSections_t, as the unordered map now keeps track of them.
* Removed all extraneous module section copies.
* Renamed 'GetImportedFunction' to 'GetImportedSymbol'.
* Renamed 'GetExportedFunction' to 'GetExportedSymbol'.
*Made a static version of 'GetImportedSymbol' and 'GetExportedSymbol', so it could be used on raw module base addresses.
*Created inlines for getting the DOS and NT headers.
*Improved formatting so the code could be read more easily on a vertical monitor.
