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.

  1) if the GL_EXT_texture_rectangle (a.k.a. GL_ARB_texture_rectangle) GL extension
  is available, no platform-specific code is needed, besides support for fl_draw() and Fl_Image_Surface for the platform.
- 
+
  2) if the GL_EXT_texture_rectangle GL extension is not available,
  a rudimentary support through GLUT is obtained without any platform-specific code.
