When shortanswer, numerical, calculated and calculatedsimple questions
did not have a '*' match-anything answer, then any student response that
did not match any of the teacher-given answers were classified as
'[No response]', which was not right.
This patch fixes that. Such responses are now classified as
[Did not match any answer].
While I was doing this, I noticed that the display of tolerance
intervals for numerical questions in the response analysis was horrible,
so I improved it.

There were already one just added upgrade.txt file so this ended
conflicting. Reviewed the contents, I've deleted the less detailed
note about pluginname, leaving the longer description added by Tim.

This applies to:
1. Upgrade from 1.9,
2. Import of questions exported from 1.9, and
3. Restore of courses backed-up from 1.9.
It also applies to the calculated question type.
Probably easiest to explain by example: If the right answer is 1.23 m with alternate
unit 100 cm = 1m then the completely right answers are 1.23 m and 123 cm.
Right answer, wrong unit responses include 1.23, 1.23 frogs and 1.23 cm.
123 m is not considered to have the correct numerical value.
We may well re-consider the way this works in a future version of Moodle.
Unit grading was not implemented before Moodle 2.0. In Moodle 2.0, the unit grading
was more permissive than here, for example 123 m would have been graded correctly in
2.0. However, I'm not sure I follow the rationale for that.
It seems that people want to be able to use <sup> and <sub> here, which
makes sense, so we need to keep radio buttons for questions upgraded
from 2.0. The dropdown menu, however, is also nice, so keep that option
too for new questions.
At least, after these changes, I was able to create a calculated question through the Moodle UI and then preview it. I am sure more testing and fixing is needed to make sure everything works.
