Add unit tests and fixes due to unit tests

Adds unit tests for AirLoopHVACUnitarySystem along with various bug
fixes due to the unit tests.
Fix failing unit test

Fixes a failing unit test in AirLoopHVAC:UnitarySystem when removing a
unitary system with coils attached to a plant loop.
Add DX coil translateAndMapModelObject 'magic'

This change allows translateAndMapModelObject to use the correct
forward translator for DX coils depending on whether or not they are
part of a containing system, such as a unitary system.

This checks if the coil is on an AirLoopHVAC (and thus use
translateFoo) or if the coil is in a containing component (and thus use
translateFooWithoutUnitary).
Add ForwardTranslateAirLoopHVACUnitarySystem
Merge remote-tracking branch 'origin/EP81' into EP81_UnitarySystem
Fix build issues
Merge branch 'EP81' into EP81_UnitarySystem
Fix translate errors found during integration test

In forward translation for AirLoopHVACUnitarySystem there were two
errors. One dealt with fan placement within the unitary system and node
names.

I also updated SetpointManagerMixedAir updateFanInletOutletNodes()
implementation slightly while tracking down an issue. Now it only loops
through all supplyComponents once to find the different types of fan
types.
Add unitary system into OS App
Bugfixes and updates

This removes the ability of the user to set and use the ControlType.
ControlType can be either Load or SetPoint, if it is SetPoint you need
to define SetpointManagers for each node within the Unitary System
which a user can no do from the GUI. So we are commenting out this
functionality for now.

This also fixes a small bug in forward translation and changes the mini
icon to an actual mini icon.
Add UnitarySystem to hvac_library

This adds various unitary system configurations to hvac_library.osm and
also updates the OpenStudioPolicy slightly.

The added configurations are:
Unitary - DX Heat Pump - Cycling - Elec reheat
Unitary - DX Heat Pump (Two Speed cooling) - Cycling - Elec reheat
Unitary - Two Speed DX cooling - Gas heat - Cycling - Elec reheat
Unitary - Two Speed DX cooling - Elec heat - Cycling - Elec reheat
Unitary - Single Speed DX cooling - Elec heat - Cycling - Elec reheat
Unitary - Single Speed DX cooling - Gas heat - Cycling - Elec reheat
Unitary - CW cooling - HW heating - VAV - HW reheat
Unitary - CW cooling - HW heating - CAV - HW reheat
Unitary - WaterToAir Heat Pump - Cycling - Elec reheat
Unitary - Elec heat - Cycling
Unitary - Gas heat - Cycling
Unitary - Two Speed DX cooling - Cycling - Elec reheat
Unitary - Single Speed DX cooling - Cycling - Elec reheat
Change UnitarySystem to not use heat recovery

After reading E+ IO reference more closely, the heat recovery appears
to only work with multi speed DX coil. So until this coil is
implemented in OpenStudio, I am commenting out the heat recovery code.
By commenting out the code, it will make it quick to enable the heat
recovery option once the coil is added to OS.

Since the heat recovery is no longer possible, I have disallowed adding
the unitary system to a plant loop.
