Bug 625601 - FORTRAN: recognition free versus fixed formatted code

Resolves the error of unbalanced tags opened/closed in docbook output

According to the documentation the .bib is automatically added to the names in the CITE_BIB_FILES. In the example given with this bug this was not the case.
In case CITE_BIB_FILES was set to 'my.bib' it was working, but with only 'my' it wasn't.

Bug 589707 - Flex .rule file for Visual Studio build can't cope with spaces in filenames

Correction in documentation based on comment by dnm on June 19 2014

Adjusted the rules files and where and the vcproj file so it can handle paths with spaces as well.
When generating the documentation (Cygwin) a small problem appeared in a Makefile when there is a space in the path, this is solved as well.

resolves the error of unbalanced tags opened/closed in docbook output: parser error : Opening and ending tag mismatch: para line 358 and tbody

Tcl: collect XRefs also if INLINE_SOURCES = no

- Open() replaced by xopen() that internally uses the encoding argument
  only for Python 3. The earlier usage of the codecs module and of the
  prefixed unicode string literals was removed.
- Some lists of prototypes were sorted to get the same translator report
  for different versions of Python.
- The local dedent() definition was replaced by textwrap.dedent().
  (The older versions of Python did not have the module.)
- Tested on Windows for Python 2.6.0, 2.7.7, 3.0.1, and 3.4.1.

Fix typo

\usepackage{fixltx2e} must come before use \usepackage{float}

The \usepackage{doxygen} statement adds float as a depenency.
If the order is wrong the latex generation fails with:
LaTeX Error: Unknown float option `H'

Fix unnecessary rules for FORTRAN user defined types

Fix description of USE_PDFLATEX

Added documentation for some missing HTML commands

Added documentation for H4, H5 and H6 command to be complete and extended IMG description a bit
