[fdo-internals] Small hack in setenvironment.sh

[Mateusz Loskot]

Folks,

I've applied a tiny hack to the setenvironment.sh script:

http://trac.osgeo.org/fdo/changeset/3952

It does not change anything in how the script currently behaves.
It just gives a small backdoor to request the script to not to create an 
installation directory. It's something like non-install mode.

Summarizing:

1. Works as expected and previously defined

$ source ./setenvironment.sh

2. Works as non-install mode

$ source ./setenvironment.sh --noninstall
$ source ./setenvironment.sh xxx
$ source ./setenvironment.sh abc123

As you see, the value of given parameter has no meaning.

I hope you don't mind I've added this hack :-)
