Removed DHTMLXTREE code residue

Grepped the code for all DHTMLXTREE related occurrences. For e.g. -
1. node['id']
2. node['text']
3. node['im0'], node['im1'], node['im2']
4. node['item']
and deleted/addressed it.

#118
For MiqAeField and MiqAeValue use build+save instead of create!

This PR is based on the Active Record/Postgres.

For Git based Automate model the MiqAeField and MiqAeValue are saved
in the class and instance yaml files and are not separate tables like
in ActiveRecord. Build followed by a save allows us to write just once
into the file as opposed to writing the file several times once a value
or field is saved.
