Important bug fixes for the PWGLF/FORWARD directory

	modified:   ../../../OADB/PWGLF/FORWARD/CORRECTIONS/data/fmd_corrections.root
	modified:   ../../../OADB/PWGLF/FORWARD/CORRECTIONS/data/spd_corrections.root

Updated corrections and include new noise-gain correction for all possible runs

	modified:   ../../CMakelibPWGLFforward2.pkg
	modified:   ../../PWGLFforward2LinkDef.h

New classes added

	modified:   AddTaskFMDELoss.C

Minor fixes for new AliFMDESDFixer

	modified:   AliAODForwardMult.cxx

Allow trigger mask "CENT"

	modified:   AliBaseESDTask.cxx
	modified:   AliBaseESDTask.h

New method PreCorrections - meant to do stuff when we know the run number etc.,
but before reading the corrections

	new file:   AliFMDCorrNoiseGain.h

A new type of correction.  This is used to add in the additional noise that
the reconstruction failed to add because of a bug in the AliFMDRawReader.  With
this, we can process old data with out fear of corruption.

	modified:   AliFMDDensityCalculator.h

Moved re-calculation of eta to new AliFMDESDFixer class

	new file:   AliFMDESDFixer.cxx
	new file:   AliFMDESDFixer.h

A class that fixes up the FMD ESD object for various flaws, including
bad values for 0's, missing noise from reconstruction, and possibly
re-calculation of eta.  This class takes an AliESDFMD object and
modifies the content in-place.  Unfortunately we cannot re-calculate
the phis in this, because we never store the phis in the ESD object.

Added new method for 2013 pA data.  Updated the method for
selecting which vertex method to use.
