The case transformation didn't work properly as the char value was not casted to an unsigned char, causing undefined behavior. Added new utility function 'IsEqualNoCase' which allows for comparing 2 strings case insensitively. Code has been tested with module strings containing irregular cases, and was still able to obtain the imported function address correctly.
* Added 'GetImportedFunction'.
* Remove extraneous std::string copy constructors during construction of 'm_vModuleSections'.
* Added extra constructor using base address.
* Promoted size types in CUtlBuffer to int64.
* Fixed bug where CUtlBuffer::GetPtr returns a 64bit pointer that was promoted from a 32bit integral type.
* Use int64/size_t for anything strlen, pointer subtraction, etc..
* Removed invalid structure alignment declarations.
Allow searching for multiple occurrences, the main reason for this addition is that some RTTI object locators reference 2 (or more) VFTables, the ConVar class is a good example., where we have 2 separate VFTables, one implementing ConCommandBase (which implements its own IConVar), the other implementing just IConVar for ConVar (2 VMT pointers in one class).
