new: support numeric appearance bearing

[florianm]

• Close Support appearance "bearing" for numeric fields #193
• Add appearance "bearing" to numeric questions
• Add a hint about bearing to context help
• Enforce attr type "decimal" for bearings

Appearances are passed through to the XLSForm export without any extra effort needed, right?

I will verify that in a tic. I suspect some unit tests might need to be adjusted.

This indeed requires an addition to build2xlsform. Coming soon. Currently we get the last option in the list of numeric appearances (range) with its defaults (1 to 10 in steps of 1) which is wrong.

Build now produces a valid bearing appearance:

      <bind nodeset="/data/q_bearing" type="decimal"/>
    </model>
  </h:head>
  <h:body>
    <input ref="/data/q_bearing" appearance="bearing">

      <hint ref="jr:itext('/data/q_bearing:hint')"/>
    </input>
  </h:body>
</h:html>

I've included a bearing question in a test form, which uploads without errors and submits fine. Screenshot of bearing question in submission tab in Central:

Aha, thanks for the thorough check.
