Added a bunch of image manipulation functions:

Browse Source 
Renamed functions (for coherence with new ones):
- ImageConvertToPOT() -> ImageToPOT()
- ImageConvertFormat() -> ImageFormat()

New functions added (IN PROGRESS):
- ImageCopy()
- ImageCrop()
- ImageResize() (Uses stb_image_resize.h)
- ImageDraw()
- ImageDrawText()
- ImageDrawTextEx()
- ImageFlipVertical()
- ImageFlipHorizontal()
- ImageColorInvert()
- ImageColorGrayscale()
- ImageColorContrast()
- ImageColorBrightness()
