Save Project and Save Analysis do not save name of first model in each list

[krzywon]

When saving projects and analyses, the names for the first item in each combobox are not saved to the project/analysis file. The categorycombobox, forfactorcombobox, and structurefactorcombobox values are given empty strings ("") instead. The loading is smart enough to try the first item in each drop down if no values are given, but as we change category names, this is starting to cause issues.

This bug exists in at least v4.0.1 and v3.1.2.

Fixes #819: Category, form factor and structure factor names are now assigned to the pagestate properly. They all are saved and loaded as expected.
