Changes to Standard Gui to allow resetting of all unit-related parameters on a new Homeostat
Added a function to HomeoQSimulation to force the units to send back update signals for all their relevant parameters
Moved management of the mass property up from Newtonian Unit to standard HomeoUnit
Moved initialization functions of Uniselector and UniselectorAshby out of their constructors to allow reinitialization of existing Uniselectors
Added a function in Homeostat>>fullReset to allow restting all units to their default values
Fixed initialization of HomeoUniselector
Added convenience function to HomeoUnit for the management of the mass property
Added allValuesChanged function to HomeoUnit to signal back to GUI changes in all relevant parameters when reinitializaing an existing unit
Added a function to HomeoUnit to broadcast signals to GUI when its relevant parameters have changed
Added a function in HomeoUnit to reinitialize Uniselector settings without switching to new ones
Added a call in the constructor of Homeounit to the new function initializing uniselector settings
ERROR in previous commit. This time: Added a call in the constructor of Homeounit to the new function initializing uniselector settings
Moved initialization of HomeoUnit to separate function to allow resetting units to default values. Solved problems with instability in previous version
More fixes on HomeoUnit to solve stability issue (a regression introduced when fixing HomeoUnit to allow updating of GUI on new homeostats)
Fixed updating of unit names in GUI and discarding of unused names from globa names set
Fixed updating of uniselector time interval in standard GUI
Fixed updating of units uniselector on in Standard GUI
Updating of unit active status after reset to new Homeostat is now fixed. Fixes #68
Merge branch 'master' into before-changing-homeounit

Master had become unasable after regression introduced in the revamping
of HomeoUnit to accomodate refreshing the GUI whe a new homoestat is created.
