[FreeNX-kNX] Bug fixes - nxclient infinite loop/session names with spaces

[Neil Wilson]

While installing freeNX 0.2.7 on a Gentoo distribution I came across a
couple of problems. They are probably applicable to all installations of
FreeNX.

Firstly if you want to use the 'nxclient' shellscript rather than install
the nxclient binary on the server then there is a potential infinite loop
problem if the shellscript is installed in /usr/NX/bin.

This is fixed by making the check for the binary client more effective.

Secondly a $@ without double quotes has crept into the script which prevents
session names from having spaces in them (the client will hang and fail to
connect, but work fine if you don't have spaces in the session name)

Hope these are of use.
