Michael Fabian 'Xaymar' Dirks e0e2d9fe80 project: Improve Linux support (#27 and #13)
While Linux was not an original goal of the project, it should still be supported out of the box. Therefore a number of changes are contained in this changeset:

- All C++ .h files were renamed to .hpp.
- All C includes (<....h>) were replaced with C++ includes (<c...>) and missing includes were added.
- std::memset and std::memcpy was replaced with memset and memcpy.
- All anonymous structs were removed where necessary.
- `extern "C"` was removed where it wasn't needed.
- #pragma warning was placed behind an #ifdef _MSC_VER
- The macros for `min`, `max` and `clamp` were removed as they were not used.
- `-fpedantic` was added to the GCC flags for bitmask support.
- `gs::rendertarget_op` is now declared before use.
- std::exception(const char*) was replaced with std::runtime_error(const char*).
- Added aligned_alloc and aligned_free macros for GCC and MSVC support.
- Replaced use of `sprintf_s` with `snprintf`.
- Placed additional guards around windows only code.

Additonally some changes were made that do not affect Linux:
- `NOMINMAX` and `NOINOUT` were removed.

Fixes: #27
Fixes: #13
