[Kst] loading equations and psds

[George Staikos]

I think I'm down to one last problem before I can commit the equation and 
psd / curve separation.  The problem is what to do about loading old Kst 
files.  We can't know if they refer to equationcurves as opposed to 
equations.  One way around this is to change the XML node name for these 
elements and leave specialized code in for reading the old nodes and 
producing a curve implicitly.  This of course won't be backwards compatible.  
The other option is to just ignore these old entries.  Any better ideas, or 
preferences?
