Bugfix: Submit/Cancel order scripting errors + Ordermanager GetOrder & CancelOrder improvements (#584)

* Fixes Submit and Cancel order functions for scripting. Adds tests to ensure that wrapper functions actually execute as expected. Adds more coverage. Fixes a few other tests

* Fixes issues

* Simplifies tests

* Update cancel order to properly cancel an order. Adds example script. Adds sweet tests.

* Fixes bad test setup for cancelling orders

* Adds new order manager GetOrderInfo function to call the wrapper function and then store it in the order manager

* Addresses order concerns

* LOWERS THE CASE OF ALL EXCHANGE NAMES BECAUSE ORDER MANAGER NEVER CARED ABOUT CASING OR YOUR FAMILY

* Removes asset and currency requirement from cancelling orders via validation test

* Fixes old cancel order assumptions that had requirements for currency and asset

* Moves all the logs and events to the dedicated Cancel function instead of exclusively doing it in CancelAllOrders

* Adds more detail logging. Fixes lbank fee test

* Addresses comms manager issues

* Removes go routine for pushing events. Better to let them fail
