Solver code maintenance

1. Fix bugs in the solver
2. modify the code to implement new algorithms (lambda, on / off rate
3. add sanity checks in the client

PR #1532 upgrading to langevin 1.4.0
what's new:

• new solver algorithm for computing lambda (from Boris), see implement Boris' new algorithm, lambda, kon, koff cam-center/LangevinNoVis01#13
• postprocessing algorithm for multiple runs (averages, min, max, std) and cluster analysis, see Dan ss cli - consolidation postprocessing entry point cam-center/LangevinNoVis01#17 and Consolidation postprocessor cluster analysis cam-center/LangevinNoVis01#19

@danv61 What's left to do for this issue?

[danv61]

This is an umbrella issue, part of the Springsalad new feature (Issue #870), covering any changes to the Langevin solver. The solver side of the development is actually finished, but I plan to keep the issue open for unscheduled modifications / fixes)
