Remove $Id$ tags, update URL's, and more

- 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.

  \brief Base class for image caching, scaling and drawing.

  Fl_Image is the base class used for caching, scaling and drawing all kinds of images
- in FLTK. This class keeps track of common image data such as the pixels, 
- colormap, width, height, and depth. Virtual methods are used to provide 
+ in FLTK. This class keeps track of common image data such as the pixels,
+ colormap, width, height, and depth. Virtual methods are used to provide
  type-specific image handling.

+
  Each image possesses two (width, height) pairs. 1) The width and height of the
  image raw data are returned by data_w() and data_h(). These values are set
  when the image is created and remain unchanged. 2) The width and height
  of the area filled by the image when it gets drawn are returned by w() and h().
  The values are equal to data_w() and data_h() when the image is created,
  and can be changed by the scale() member function.
-  
+
  Since the Fl_Image class does not support image
  drawing by itself, calling the draw() method results in
  a box with an X in it being drawn instead.
