Many thanks to @darealshinji for contributing all the code
for this new FLTK image class (see branch Fl_ICO_Image of https://github.com/darealshinji/fltk).
The new function fl_write_png() was moved to its own file and is now
publicly available ("exported") so other programs can use it.
This function was used in fluid to write a window screenshot (.png)
together with a template (.fl) to preferences storage.
- remove obsolete svn '$Id$' tags from all source files
- update .fl files and generated files accordingly
- replace 'http://www.fltk.org' URL's with 'https://...'
- replace bug report URL 'str.php' with 'bugs.php'
- remove trailing whitespace
- fix other whitespace errors flagged by Git
- add and/or fix missing or wrong standard headers
- convert tabs to spaces in all source files
The only relevant code changes are in the fluid/ folder where
some .fl files and other source files were used to generate
the '$Id' headers and footers.
This constructor has a 3rd argument, the size of the array holding the in-memory PNG image.
This allows the constructor to check for errors in the image.

classes: new copy(), copy(w,h), desaturate(), color_average(), and
inactive() methods, alloc_xyz member for copied data, etc.
Updated test programs to use inactive() and copy() methods to create
inactive images for the test buttons, plus the inactive button to toggle
it...
Added start of separate image classes, a la 2.0, for various image formats.
FLUID will also be updated for it...
