1dfe431c00 Eeschema: enable tunable VDC, IDC sources in sim 
ADDED: Eeschema SPICE simulator now supports tuning VDC and IDC
sources.

Adds ability to interactively tune VDC and IDC sources in sim.
This allows users to quickly test bias/supply changes during
transient simulations.

c22eac2fbf Performance. 
Saves about 30% of the time to open the sim model
dialog.  Pretty much all the remaining time is in PEGTL,
and that's even with short-circuiting it for most param
values.

4b1fc9c129 Update AM and SFFM source parameters to ngspice-43. 
Note: there's no migration strategy because they didn't
work at all prior to ngspice-43.

7c5eaed69e Un-comment and repair TRRANDOM sources. 
Also adds new parameters to AM sources for ngspice-43.

Also fixes a bug in the spice parameter parser (which would
puke on any parameter name starting with one of the flag
parameter strings).

Also fixes a bug where the skipped source parameters would
get set to "0" instead of their default values.

39a1b14a0f sim: VSIN - allow user to specify a phase 
TD is not the same as PHASE.
TD is the delay before the source turns on.
PHASE is ... the phase

If only TD is set, the signal starts later, but the phase is still 0 when compared to the t=0 of the simulation.

6b70c679cf Migrate more V6 SPICE syntax to V7. 
Also fixes various bugs if symbols contained non-indexed pin numbers.
We really need to know the actual pin names when creating models, rather
than just assuming 1, 2... etc.

integers and are the same as indexes in the vector storing the symbol
pins.

"~" is now used to denote a floating sim model pin.
