Some functions/values have been deprecated for long time but some mapping was kept for convenience. Some of those mappings have been removed...

RENAMED: GetCodepoints() -> LoadCodepoints(), now codepoint array data is loaded dynamically instead of reusing a limited static buffer.
ADDED: UnloadCodepoints() to safely free loaded codepoints
RENAMED: GetNextCodepoint() -> GetCodepoint()

* fix text wrapping

* fix indent

* fix indent

* fix indent

* fix DrawTextRec

Replaced: Returns -> Get

Some enums values have been renamed to be more consistent and also provide a more detailed description:
 - ShaderLocationIndex:    LOC_VERTEX_POSITION -> SHADER_SHADER_LOC_VERTEX_POSITION
 - ShaderUniformDataType:  UNIFORM_VEC2 -> SHADER_UNIFORM_VEC2
 - MaterialMapType: MAP_ALBEDO -> MATERIAL_MAP_ALBEDO
 - PixelFormat: UNCOMPRESSED_GRAYSCALE -> PIXELFORMAT_UNCOMPRESSED_GRAYSCALE

RENAMED: TextureFilterMode values
RENAMED: TextureWrapMode values

Previous implementation did not consider any padding while drawing the characters on screen (despite being available on the font atlas), so, only minimum character area was drawn.

If some text effect shader was required (shadow, glow, outline...), there was no space in the drawn quad to draw that pixels effect.

This commit corrects that issue.

This is a BREAKING CHANGE!

To address the linked issue, several functions have been renamed and couterpart functions have been created to free loaded memory:
 - RENAMED: GetImageData() -> LoadImageColors()
 - RENAMED: GetImagePalette() -> LoadImagePalette()
 - RENAMED: GetWaveData() -> LoadWaveSamples()
 - ADDED: UnloadImageColors()
 - ADDED: UnloadImagePalette()
 - ADDED: UnloadWaveSamples()

When .fnt file is in the .exe path, image path was wrongly calculated

- LoadFontDefault() -> Some code simplifications
 - LoadFontFromImage() -> Avoid LoadImageEx()
 - LoadFontData() -> Avoid GenImageColor(), ImageFormat()
 - LoadBMFont() -> Avoid ImageCopy(), ImageFormat()

Removed ImageAlphaMask() dependency on [text] LoadBMFont()
