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 Directs all graphics requests to an Fl_Image.
- 
+
  After creation of an Fl_Image_Surface object, make it the current drawing
  surface calling Fl_Surface_Device::push_current(), and all
- subsequent graphics requests will be recorded in the image. It's possible to 
- draw widgets (using Fl_Image_Surface::draw()) or to use any of the 
+ subsequent graphics requests will be recorded in the image. It's possible to
+ draw widgets (using Fl_Image_Surface::draw()) or to use any of the
  \ref fl_drawings or the \ref fl_attributes. Finally, call image() on the object
  to obtain a newly allocated Fl_RGB_Image object.
  Fl_Gl_Window objects can be drawn in the image as well.
