Following items are added/corrected.
1) Clicking on Vrouter when other vrouter is already selected doesnt highlight new vrouter
2) show list of interfaces & if_indices - included in tooltip
3) more_attr in links is array now, so changed to code.
4) Some places 'more-attr' is used and in some places 'more_attributes' is used.
We decided to use 'more_attributes' everywhere. Changed the reference of this
term in UI.
