Changes

* Fix for bug #21754 (https://gna.org/bugs/?21754). This is the failure of the [http://www.nmr-relax.com/manual/grace_view.html grace.view user function] on MS Windows in opening a file in qtgrace when the path includes spaces, as reported by Mengjun Xue (mengjun dott xue att mailbox dott tu-berlin dott de). The fix was to run the program with the file name in double quotes.

* Fix for bug #21763 (https://gna.org/bugs/?21763). This is the problem of the chi2 value not being visible in the parameter list of the [http://www.nmr-relax.com/manual/grace_write.html grace.write] and [http://www.nmr-relax.com/manual/value_write.html value.write] user functions in the GUI. The problem was that when asking for the parameter name list, the minimisation parameters were not being asked for.
