add preliminary support for exinda / gfi traffic shapers (#283)

* exinda support

* exinda support

* add exinda hint

needed to identify exinda devices.

* mentin exinda in overview and link docs

* overwrite layers to l2/3/4/7

* get uptime from exinda mib

now matches uptime reported by cli & web interface.

* single quotes preferred

* to much copy/paste

* merge 3.63

* some more functions added. also general cleanup

* Update .travis.yml

* a few fixes
