Bugs when loading database vis combined with dynamically created

[OKaluza]

Due to id clashes in colourmaps and objects

Can be solved by clearing existing object and colourmap lists before gldb load, then re-appending to end of list, but will need to use std::map for colourmaps and access by name not id

This is causing problems, needs to be fixed for next release: use case:

• create static vis objects, then load database problem:
• static object data ends up sharing object id with those from database

Bug is in json state load - imported objects/colourmaps are matched by index not name
