Live Data: Implement LiveListenerManager & LiveListenerFactory

[Russell Taylor]

As described in ​https://github.com/mantidproject/documents/blob/master/Design/Live_Event_Data_Detailed_Design_Document.doc

These will be very similar to the AlgorithmFactory/Manager.

[Russell Taylor]

Add LiveListenerFactory first version. Re #4801.

Deviating from what's currently written in the design document because: (a) I don't think that maintaining listener lifetime here and handing

out references to existing listeners will work out well - e.g. if two MonitorLiveData instances were created they would 'compete' in calling ILiveListener::extractData.

(b) Even if we did there's no need for a separate LiveListenerManager

class (see UnitFactory which does the same thing).

Add live listener field to FacilityInfo. Re #4801.

A few minor tidy-ups alongside that.

Re #4801. Expand FacilityInfo unit test.

Let to a little refactoring in the class itself. In particular, removed an assumption that instruments always have uppercase names.

Re #4801. Add live listener details to InstrumentInfo.

Read in from facilities file.

Re #4801. Clear warnings that don't show up in a debug build

...for some reason. The warnings are plain wrong anyway - I notice that newer versions of gcc are smarter.

Re #4801. LiveListenerFactory looks up listener from instrument name.

The create() method takes in an instrument name and will look in the InstrumentInfo object for the live listener class to create and the connection string to call ILiveListener::connect() with.

You can still pass in a concrete listener class name as well, so existing tests will still work.

Been playing with the Live data stuff for about a day trying to break it. Seems to be very stable, been running 7 instances, all with preserve events=true, and all seems happy.
