- 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

Makes Synplify for iCE40 want to implement buffer in RAM but then fail
due to reset.

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

For future latency estimation

This includes generated files apart from the instrumented netlist.
The latter just gets a header stating which version of FIJI generated it etc.

Also rename existing licenses to include a .txt suffix and
the license's version.

 - add version string
 - refer to project website

FIJISettingsViewer and FIJITestsViewer are widgets and can refere to
their root windows via $self->MainWindow thus there is no need to
store them additionally.

I broke it in commit 0c9547b4.

Even in the case the number of FIUs stored in the settings file (FIU_NUM)
differs from the actual number of FIUs therein, set it to the actual value.
This essential degrades it to a simple size value of the respective fius
array but avoids any confusion in the code.

Before some hash key/value pairs have slipped without being
initialized at all. This caused for example:
"Use of uninitialized value" warnings in FIJITestsViewer.pm line 1137

Does not do what the commit message says at all.

Since there is no way to supply a netlist in FIJI EE it cannot verify anything
related to the netlist, e.g. external port names. However, they are more
or less moot anyway during download because we rely on the design ID
to detect any mismatches between the (actually downloaded) netlist
and the configuration.

Else some hash key/value pairs are not initialized at all.
This causes for example:
"Use of uninitialized value" warnings in FIJITestsViewer.pm line 1137

With this change we also set the defaults unconditionally when loaded
by the GUI. This also requires $global_settings_ref to be passed to
_set_defaults() which was using an inexistent $self->{'settings'} so far.

It does not matter though... no idea how to set the reason for failing
runs.
