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.

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)

Which patch 8e8c9a1e (dd. May 6) the rule:
<Start>{FLOW}/[,( \t\n].*
has been changed into"
<Start>{FLOW}/[,( \t\n]
(analogous: <Start>{COMMANDS}/[,( \t\n])
To overcome the warning: fortrancode.l:744: warning, dangerous trailing context.

The result is that the code coloring of (e.g.) the if statements in:
      subroutine test_on_if
        if (a == b) then
          c = d
        endif
        if(a == b) then
          c = d
        endif
      end subroutine
was removed, due to the fact that the rule: <Start>{ID}{BS}/"(" was used instead of the flow coloring rule.

This patch fixes the rules so the lines are colored again and there is no warning.
