Removed dependency on Blitz

Bug 1000: AntennaField moved back to APL/APLCommon so LCS/ApplCommon does not depend on blitz Arrays. LCS/ApplCommon
has a AntField class now that contains the logical that used to be in the AntennaField class. The 'new' AntennaField
class uses the AntField class to readin the information and presents it as a blitz-array.

Added synonyms msin.name and msout.name (for SAS/MAC)

Updated for new NDPPP parameters

Initialize depending on station type

Initialize arrays depending on station type

Use backtrace possibility

Optionally accept non-existinf AntennaField files

Bug 1491: Fix for bug reported by P. Serra, trying to flag on Stokes Q in a 2 polarization (XX,YY) set did not work.

Use I shapelet for undefined other shapelets

Bug 1491: Fix of somewhat confusing side effect of the dilation operation when the Equal polarisation setting was removed. Reported by A. Biggs.

Bug 1491: Fix of bug reported by A. Biggs: it was not possible to write individual polarizations to a set -- the tools would always write the first mask (XX normally) to the set. Default strategy was not affected.

Bug 1681: Print which configuration files are being read. This cannot be done using the logger, because it is not yet configured at that moment.

Made it possible to use an expression in nchan for startchan and nchan
