MultiSelect optimization/bugfix

[pl0xz0rz]

This PR:

• fixes a bug where selections for multi-selects are invalidated when an unrelated derived column change - bokehTools.py - the bug was introduced in #212

• Adds a simple dependency tree for derived columns on the client, optimizing recomputing them as a side effect by saving some garbage collection time - CDSAlias.ts - this should also make derived columns update properly when dependencies are changed, preparation for making the text input widgets as discussed in ATO-595

• Fix problem with suboptimal performance of parametric aliases - reported in ALICE fastCombinator tracking use case

  • https://alice.its.cern.ch/jira/browse/ATO-595
  • avoid multiple updates (1 update instead of the ~ 10 updates - number of multi-select widgets in dashboard)

Hello. Could you please explain in the first message - why this new feature was implemented (parameterized aliases) and point to the code segment -where this javascript dependency tree was implemented
