When everthing else is given absolute, using a width relative to
\textwidth easily produces problems...

Command line used was:

The target to produce an intermediate .aux file for latex documents
was removed in 071d7b5c to simplify the build without taking the overall
docs/ makefile into account. The latter relies on a destinct target for
.aux files.
This commit adds it back but makes sure that failed attempts to build it
still get retried by using pdflatex' drafmode (which does not write the
PDF file itself).

Also, fix some other minor issues in the makefile and the generation of
the directory of acronyms.

 - fix bottom right copy&paste error
 - make sure all text is FreeSans (not Nasa)
 - make fonts a bit smaller to fit better between pins

The previous version sometimes failed to rebuild a document after a
failed build attempt followed by a correct fix.

Added trigger to UM.

Added constraint files for Vivado.

Added FIU names to cfg

Added template qsf for FIJI pin constraints
Added FIU names
Added connection figure to user manual section

Also, add some missing strict/warning statements and fix resulting
warnings and refine some comments in the headers of files.

The FIJI version string is stored in the root directory on file VERSION.
This is used in the following places:
 - doxygen uses it as PROJECT_NUMBER (passed as an environment
   variable set by the docs/makefile picked up by the doxyfile)
 - FIJI.pm defines and exports a FIJI_VERSION constant
 - FIJIUtils.pm inserts it for all occurrances of $FIJI_VERSION$ in the about text
 - the UG and TRM show it on their cover pages
 - FIJI/VHDL.pm, Constraints.pm, Netlist.pm put it in all generated files
   (additionally also the design ID is printed where it wasn't before)
 - all "executables" report it in the first log message

Files will be rotated once a day or if they grow to 100 MB up to 7 stages.

 - add new log files to .gitignore
 - refine documentation and install scripts
 - refine log level of "Starting/stopping execution..." to become visible
   in rotated logs
 - minor other log refinements
