Ietestform journal feedback

[kbjarkefur]

Two changes based on feedback from the Stata Journal reveiw:

• use using instead of surveyform(). Backward compatibility is built in.
• rename report() to reportsave(). Backward compatibility is automatic thanks to option name abbreviation.

I have tested this and the changes are not that big. But if someone else could test this too, then that would be great! @roshni13khincha , could you test since you have used this command before?

I duplicated my comment. Ignore this one and read the following.

I have tested the new features and they work. However, I've come across two minor things:

1. If a file extension is not specified for the report, the command will save it without one, and no warning/error message is given:
   

2. The date option is not working

3. Special characters (argh) may be imported with the incorrect encoding -- not sure there is a way to fix this, really, as one would have to be able to tell how the file is encoded before importing.
   

I think I've fixed 1 & 2 in 469e56c, so I'm approving this and opening an issue for 3in #112 that we may look into later if anyone has ideas on how to fix.

Thanks for fixing 1 & 2. I will comment on 3 in the issue you opened.

I will go ahead and merge now.
