#9 deploysite too restrictive

[Steve Meyfroidt]

The deplotsite target is rather difficult to use "as is"
since it assumes quite a lot:
* the name of the ssh/scp binaries (don't match
PuTTY's executable names on Windows)
* that no password is required (does the ant "exec" task
not pipe stdout/stdin to the console?)
* that the command options are (for example) "-
oProtocol=1" which again doesn't match PuTTY on
Windows.

Suggest that this task be made much more flexible and
substitute user-defined properties to change such
behaviour?
