[Olly Betts]

After a Summer hiatus, here's Survex 1.0.14:

I've also built the versions for RISC OS and MSDOS on 286 or earlier
machines this time - sorry about the lack of builds for these recently -
I have to build them on a different machine, which takes extra time.

This version introduces svxedit, based on xtherion from Therion.  It's
not fully formed yet - think of it as an early version or prototype and
tell us what you'd like it to be.  Thanks to Stacho Mudrak for sorting
this out quickly so it could go in this release.

Here's the usual summary of changes in 1.0.14:

* svxedit: This is a Survex data entry editor from the therion team.  It needs
  tcl and wish installed - for MS Windows an installer is available for free
  from Activeware.

* Improved handling of Compass PLT files and CMAP xyz files - no longer change
  dots to spaces in survey and station names - instead use a space as the
  separator between survey name and station name.

* aven: when picking non-overlapping labels, show a slight preference to shorter
  labels with the aim of displaying more labels.

* aven: fixed hard to notice problem which could cause the cave to appear
  tilted sideways after a lot of manipulation.

* cavern: Modest speed improvement (0.5% for sample dataset).

* cavern: fixed a rarely sighted bug which caused erroneous error about some
  stations not being attached to a fixed point.

* cavern: fixed clino readings and DIRECTION to work in interleaved data.

* cavern: improved error reporting when an invalid value is given for a
  DIRECTION reading.

* cavern: fixed "singular matrix" error when very low SDs were specified.

* print*: if the --raw is used, the survey can now use the space this would
  have taken up.

* Reading of ASCII 3d files now copes with MSDOS/MS Windows line endings
  once again.  Added regression test for this.

* (MS Windows Version): Programs run from the command line now find message
  files without SURVEXHOME needing to be set.

* Updated documentation.

Cheers,
