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

The tag is USE_PDFLATEX, not LATEX_PDFLATEX

make.bat: change current directory

Removed not implemented HTML commands from documentation

This concerns the BODY and MULTICOL tags.

- it failed when one of the doxygen.exe was not present

added reset of var Dir_Old at the end.

amendment for switching between drives and flipping back to initial cur dir at end of make.bat

First thing after calling make.bat: switch current directory to folder make.bat resides in.
Purpose: easy external call of make.bat.

Bug 730418 - man page extension is incorrect

Test in respect to handling extension was tone wit equal less than / greater than sign and should only be less than and greater than. Resulting in the fact that in case of a chosen extension starting with  .0 or .9 an 3 was pre-pended.

- Fixed highlighting defined type in variable declarations
- Corrected parser state following docBlock closure

Highlighting corrected for case statements without new line (regression)

Coded coloring of flow statements corrected (regression)
