fixing some optivis node convention issues. Adding other components and trying out aLIGO plotting, nearly working. Other ROM updates too

Attempt at fixing referencing issue when deep copying the various pykat objects. It was an issue because they create dynamic properties for classes on the fly depending on which components are added, e.g. so that you can do kat.m1. However on copying the class definitions also need to be deep-copied by creating a new class and copying over the properties.

fixing mod order setting, adding in new progress parsing so less error prone, must be used with latest kat version, adding cmd_ags option so that other flags can be passed to kat.run(), like enabling coupling reduction

Adding in map reading/writing class and updates to various gui components, trying to get rotation working but failing so far

Daniel changed Param to AttrParam for alpha in beamSplitter - seems to have broken FINESSE, so I changed it back

Also change SIFlaot to pass through 'None'

This solves the issue that not in all cases the
value of 0 can understood as 'not set'.
