smurf: Update list of CSO fits.

I updated the list of CSO fits to include the period 20140829 to
20140903.
smurf: Update list of nights WVM is unusable.

Added 20140830 to the list of nights the WVM should not be used by default.
Merge branch 'master' of github.com:Starlink/starlink
kaplibs: Correct handling of _char data in kpg1_hsect.f
pubs: Allow P61 to be built without overwriting poster
hds: Fix formatting of prologue in dat1_import_floc
smurf: More fixes to support mask freezing in skyloop
ast: Ensure trailing newlines are ignored when storing FITS cards
gaia: allow more space for readouts in XY histogram

also change packing so that making window wider increases the width of the readouts
ast: Correct bug that caused astRegBaseMesh to fail with Prisms
extractor: update the version of SExtractor to 2.19.5.

This is just an attempt to update the code base and keep the existing
abilities. New features such as model fitting, PSF and galaxy, have
not been looked at and are configured out of the build (this avoids
having to look at all this, and also include ATLAS as a dependency,
externally that would be embarrasing, and internally hard to justify
and build). This could be returned to if there was any interest, but
that is probably best left to vanilla builds of SExtractor and PSFEx.
gaia: change MEF extension numbers to match new EXTRACTOR.
hds: Fix weird typo in datRef "xyz" should be "..."
hds: Use public API in Fortran wrapper

Use the public datImportFloc routine for the HDS Fortran wrapper
just like any user of the HDS API would from C for Fortran.
This allows the same code to be tested inside HDS as outside.

DAT_WHERE is anomalous in that it has no public C interface
and the wrapper requires knowledge of internals such as INT_BIG
and dat1emsSetBigi. If DAT_WHERE was removed from the HDS API
the entire Fortran wrapper would be implemented using public
APIs.
smurf: Allow fakemap to be included in unimap data

See new parameter FAKEMAP in the tounimap.py script.
gaia: improve description of data limits used in the XY histogram
hds: Remove debug printf statement
extractor: update build system for extract/src submodule

Missed out version update on previous commit
gaia: another go at describing data ranges in the XY histogram
smurf: Diagnostic to display values for samples in a given map pixel

See diag.table in smurf_makemap.def
