* Added rudimentary SVG support. Added 2 functions ImageLoadSvg and ImageLoadSvgWithSize.

* Added an example on how to use ImageLoadSvgWithSize and adjusted Makefiles accordingly.

* Added actual correct example file.

* Reviewed the code to keep the raylib coding conventions in mind.
Moved the LoadImageSvg() code into LoadImage() guarded by SUPPORT_FILEFORMAT_SVG.
Renamed LoadImageSvgWithSize() to LoadImageSvg().
Added a LoadImageSvgFromString() function to parse the loaded SVG into an actual image. This does the bulk of the work.

* Fixed typo.
