Add Steady State (COPASI-style) to VCell through CVODE (VCellODE)

[CodeByDrescher]

Adding Steady State to VCell Release in a profound way means clearing a number of large hurdles:

• Adding Steady State capability to the VCell-ODE project .
• Adding relevant GUI windows, components, widgets, etc. for users to seamlessly run steady state. (see Steady State UI changes #1553)
• Adding results window specifically for steady state results.
• Expanding solver input files to request steady state.
• Extending / adding new output file parsing for steady state results.
• Integrating new Steady State capabilities into VCell SedML import Export.
• Expanding VCML and BioModel to accept the new Steady State simulation settings.
