Bug-fix: in prior probabilities of class (processor.h), the inverse accumulator was calculated incorrectly.

Bug-fix: multi_logit/server.h calculation of prior class probabilities already included division by accumulator so it was done redundantly twice when prior class probability was used to calculate posterior probabilities per respondent (when creating resulting dataset).

Minor refactoring: multi_logit/server.h, taking out (experimentally) potentially redundant (given practically realistic number of classes and their estimated probability values) the "multiplicative by 1000" mechanisms.
Minor refactoring/feature-addition: WebGUI -- the LC model now also (in addition to the fixed theta) shows the 1st theta's prior-probability characterisations for the upcoming estimation process.
WebGUI CSS update -- better visual distinction between alternating jobs.
VCGW change -- experimental code to "sync" the progression of each dimensions' respective outer to inner (termination) ranges (i.e. by virtue of shrinking-control -- whereby the least shrunk and the least-progressed dimension limits the final progression ratio for the other dimensions).
