Treenames used as keys

[westram]

• treenames of trees stored in are used as keys, cause the current -structure is:

  /tree_data/XXX/
  

  where XXX is the name of the (e.g. tree_demo)
• the structure should be changed to

  /tree_data/tree
  /tree_data/tree/name with content XXX
  

  cause keys are a limited ressource

• Needed changes:
  • access code
  • write a fix, which once changes the way trees are stored (see nt_check_database_consistency)

• blocks #240
• blocked by #143

---

Same problem exists for

• configuration names (AWT_insert_config_manager)

[westram]

• as well move node entries to extra subcontainer (e.g. nodes)

[westram]

When changing layout:

• be careful to catch all occurrances, where -name is read from using GB_read_key(treecontainer)
• before changing it, implement #143 and increment version

[westram]

• implement together with #155
