Remove excessive warning messages

This release removes error logging to the Zorro window when calling brokerCommand with flags that are not supported. The plugin will silently inform Zorro whether the command is supported or not.

Fix colliding OrderIds

OrderIds generated to keep track of trades could collide when running multiple instances of Zorro, using the IG plugin. This has now been fixed.

Stability fixes and support for setOrderText

Fixed an issue which could sometimes cause Zorro to freeze
Also added support for brokerCommand SET_ORDERTEXT which means you can now set different order text for your different strategies. This in turn makes it easier to historically follow PnL per algo.

Minor update

Small fixes, spelling corrections etc

Add version number to jar file

I've been stupid enough to omit updates to the jar version number, which makes tracking bugs difficult. This fixes this issue

Fix error when multiple accounts exist

The Account parameter of the BrokerAccount is sometimes populated, but currently not in use.
Rather than returning an error when the parameter has a value, just ignore it.

Fix Zorro freezing issue

Fixed some instances where a value would not be returned to Zorro after placing buy/sell orders, causing it to freeze.
Also improved logging
