* Return global pointer with 'KeyValuesSystem()'.
* Declare 'bCreate' as false by default for 'GetSymbolForString()' and 'GetSymbolForStringCaseSensitive()'.
* Added vftable interface for 'IFileSystem::RemoveSearchPath'.
* Added hook for 'CBaseFileSystem::AddSearchPath'.
* Added hook for 'CBaseFileSystem::RemoveSearchPath'.
* Added method in KeyValues for loading a KV file and parsing it via the game exe (loads from cache, vpk and disk).
* Added method in KeyValues to parse GameInfo.txt when the engine loads this.
Moved every pattern to IDetour interface. This allows for debugging patterns scans more easily, and create threads during pattern searching (Operation is now fired in APIENTRY).
Also cleaned up some unused code/extraneous comments.
Slightly increased performance by purging duplicate patterns.
Made variable search less dependent from other results (except if pattern-to-scan results is within the same header)
Migrating to this to initialize all patterns and prototypes in Systems_Init() instead.
This should make debugging missing/not found patterns easier and allow for opting out variable/constant search (some of these require other patterns to be found, thus resulting in seg faults..).
Also added check to detect if user has a eligible CPU to run this SDK.
The game requires SSE and SSE2 instruction sets. Our SDK requires this too due to the use of SSE intrinsics, so we cannot let the game handle this. We have to check it ourselves.
* Move most definitions to implementation file to avoid recompiling whole program for small changes
* Pass strings by reference for where possible.
* Split Module class to dedicated file.
* Add const qualifiers to all eligible methods for address/module class
* Some renaming
