iefolder : fix issue #124 - adds a part in iefolder that goes well with the new command ietoolkit

Issue 124 iefolder - merge the branches with the two components to this issue

also fixed typos in error messages (varaiables instead of variables)

Issue #124 i- create ietoolkit command and edit iefolder so that master dofiles take advantage of this command

from "uniqely" to uniquely

This reverts commit 3fb6cfa.

The issue in the display of row titles for t-tests and normalized differences reported in the review of the pull request (#128) is caused by the titles for the two being created in the same loop. I'm deleting only the part that generates the titles.

Now the title rows are displayed correctly. But the code is not very efficient.

Option 1: different programs for ttest and normdiff with and without control_used. This will give us 4 different programs in the end

Option 2 (which I prefer): write two commands, one for the header when control option is used and one for when it's not used.

One could still make this even smaller, with a single command for both options, but not sure how much easier or harder that makes the understanding of the code

If F-test for joint significance of balance variables is used, but neither the t-test or the normalized difference are displayed, then the columns for comparison between treatment arms are not created, and the F-test cannot be displayed.

This commit (1) displays an error message if option ftest is used along with nottest, and normdiff is not selected, (2) disables option ftest, (3) still creates the balance table.

Because we have two F-tests now, it's necessary to explain what's the difference between the two of them.

We already had one f-test option, ftest, whose format was modified by pftest and starsnoadd. This commit makes it so these options also apply to feqtest
