Survex 0.99 prerelease 9 available

[Olly Betts]

This prerelease is available for all platforms except MSDOS on pre-386
machines and RISC OS (I'm going to try to build these tonight and upload
tomorrow):

This version would be 0.99 itself, but for the fact that there have been a
lot of changes since the previous version which I like to get a wider
testing.  So please hammer away.  All being well, my plan is to release 0.99
on Monday or Tuesday and 1.0 next weekend.

I believe this version fixes all the notable bugs and niggles (most of the
changes are in aven).  I've not had time to recheck my mailbox yet - if
there's a problem which you've reported and isn't fixed, please prod me
again to make sure it isn't missed.

The translations aren't all fully up-to-date.  If you're using a non-English
version and see a piece of untranslated text, feel free to help out those
maintaining the translations by sending me a translation for it.

User-visible changes between 0.99-prerelease8 and 0.99-prerelease9:

* aven: Side Panel can now be dragged or toggled shut and then reopened
  again; double-clicking on the divider now maximises the survey window rather
  than the side panel.

* aven: .3d files can now be loaded using "drag and drop" from MS Windows
  Explorer, and X filemanagers which support XDND (e.g. Konqueror).

* aven: fixed problems with selection handling in survey tree.

* aven: Escape cancels distance measuring line; suppress distance measuring
  line during auto-rotation and animated tilting.

* aven: entrance blobs now green to distinguish them from stations matching
  search.

* aven: problems with dragging scalebar fixed.

* (MS Windows version): aven: Loading file on start-up now works!

* (MS Windows version): aven: Delete now works in the search box.

* (Unix version): aven: Highlight current station in tree with grey background
  (don't seem to be able to use bold like we do on MS Windows).

* cavern: Fixed handling of interleaved nosurvey data.

* cavern: Diving and cylpolar styles now take DEPTHCHANGE where they used to
  take DZ.

* (MS Windows version): Installer now uses a different compression
  method (bzip2) which reduces the download size by about 5% (and 
  should help keep the installer small enough to fit on a 1.44M floppy).
  Bzip2 is a little slower to uncompress, but not appreciably so on the
  machines I've checked it on.

* (MS Windows version): Should now install without errors for a
  non-admin user on MS Windows NT/2000/XP.

* (MS Windows version): Installer should now allow installation on NT 3.51.

* Updated manual (notably added documentation for interleaved data styles).

* German and Brazillian Portuguese translations updated.

Cheers,
Olly
