Categoricals to take interactions instead of variables.
This change alters the API of categoricals_create, so as to
accept an array of interactions instead of an array of variables.
Currently, however only interactions which contain exactly one
variable will run correctly.

format: Use max width for over-max decimals in fmt_fix().
In fmt_fix(), requesting more decimals than are possible did
not increase the width at all. It makes better sense to use
the maximum width and maximum decimals for this case, so this
commit makes that change.

GLM: Allow +/- .001 for Corrected Total Type III Sum of Squares.
Jeremy Lavergne <jeremy@lavergne.gotdns.org> reported that on
Mac OS X this value is calculated as 329.628 instead of
329.627. John Darrington said that he's seen the same on
GNU/Linux depending on compiler optimization flags.

Jeremy Lavergne <jeremy@lavergne.gotdns.org> reported that
mktemp on Mac OS X does not have a -p option. But I don't see
a reason to use mktemp at all here, so this commit uses a fixed
name instead.

Implemented the POSTHOC subcommand for the ONEWAY command.
Currently, only LSD, Tukey, Bonferroni, Scheffe, Games-Howell
and Sidak are supported. These are presented as Multiple
Comparisons - the Homogeneous Subsets are not yet implemented.

New widget PsppireValChooser.
This widget provides a user interface allowing the user to input the
a value, or range of values. This was previously done "by hand" in
the recode dialog, but was awkward to maintain, and clumsy. Upcoming
dialogs will need something very similar. So now seemed like a good
time to encapsulate it.

Fix bugs deleting temporary files and their containing directory.
The clean_temp module provided by gnulib doesn't cleanup on program
exit. We must do that ourselves. Secondly, the close_temp_file function
was supposed to remove the file, but didn't do that. Thirdly, files
were not being registered with the clean_temp module on creation.
This change fixes these problems.

Change the order of the reported NPAR values in two sample related tests.
This change makes the order of the reported values follow the order in
which they were entered in the syntax. The changes to the tests affect
only the order. The numbers are unchanged.

The changes to t-test.at in this changeset affect only whitespace

GLM: Add unimplemented subcommands, and add a test.
This change adds a basic GLM test for the "Latin Square" use case.
It also implements the more common subcommands that might occur in
a real life example of such usage. The /DESIGN subcommand differs
slightly from spss. In spss, it is optional, and if given can be
empty. In this change, /DESIGN is mandatory and may not be empty.
The rational for that, is that spss's default is to include interactions
for all the factors. We don't (yet) support interactions, so it's
better to refuse to run a syntax which relies upon the default
rather than to run it with different semantics.

gui: Eliminate some dependencies on the dictionary.
Previously all of the dialog boxes used by the variable sheet
kept around a pointer to the dictionary solely to obtain the
dictionary's encoding. Previous commits have eliminated that
use, so this commit gets rid of the dictionary members.

gui: Simplify value_to_text() parameters.
Both the format and the dictionary can be inferred from the
variable being formatted in every case in the tree but one, so
use that as the calling convention. In the one remaining case,
it's just as easy to call data_out() directly.

sys-file-reader: Reduce invalid format from error to warning.
gaby jongenelen <geebie21@gmail.com> provided a .sav file
written by "MS Windows Release 13.0 spssio32.dll" that had
zeros in the "write" format field for several numeric
variables. Until now, PSPP treated this as an error and
rejected the file. This commit changes the error to a warning
and suppresses the diagnostic entirely for this case of a
zero value.
