Trying to tidy main function --
Fixed bug in re_home string generation --
gitignore
Rename von webtoolkit_unix_showcase in webtoolkit-unix-showcase
Changed second-stage script methodology --

The second stage scripts now just define an sc_start function with a fixed
prototype.  The first-stage script should source the second-stage script and
call the function with the appropriate parameters.  This makes the second-stage
script much more testable.
Stage 1 uses new stage 2, and nicer solicit --

The first-stage start-up script uses the new second-stage start-up scripts.  It
is a little messy still, but at least it is consistent, builds and runs.

I also changed the solicit choice function a little - it waits for input on the
same line as the request rather than after a newline - and changed the unite
test accordingly.  It is a small change, but it makes a big difference to the
clarity of the user session.

  gitignore
Modified .gitignore --

Francois put .gitignore under git control.  I modified it to ignore Vim and
airtime files.
Reinstated test to build --

I have reinstated the test stage to the Maven build, and modified the one time
start up function of the list directory content test script to clear the
testbed if it still exists when starting the test.
