The m_imageData buffer in the BITMAP_BASE is an
internal implementation - the public API to persist the
data to a stream appears to be SaveImageData - so use that,
which hides the implementation (and generates the image data
"live" when needed).
Remove the public access to the m_imageData buffer as it isn't
needed for public use, and also is misleading.
Also break out the formatting of the data into KICAD_FORMAT,
as it's currently replicated in eeschema/pcb/pagelayout
formatting code.

Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Also fixes a bug where the pretty printer didn't insert
linebreaks for a forest (it assumed a single tree root).
Also further regularises bool and quote formatting.
- Keep original image data. When loading JPEG, this avoid recompression
that changes file data and decreases image quality
- Allow schematic and page layout editors to store non-PNG data as well
- Move page layout editor to store base64 instead of hex-coded data
They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.
The editor has an entry to set a comment associated to a graphic item.
It is only for the designer, but the code to save it in .wks file when not empty was missing.
The code to read it exists since the beginning, so no change in file format
Keeping them in base_units means that we can't introduce
any dependence on these functions to anything that needs to
compile without one of the unit defines (EESCHEMA, PCBNEW, etc)
