With default values, and with calculated values

[MartijnR]

I committed 3 forms straight to master to get the repo started. I thought it might be a good practice to try to keep forms short and divided one original long form into 3 forms (empty, calculated, default). They could easily be combined though if that's preferred.

Some widgets may not be helpful, in particular: image, audio, video because the underlying files are missing (and the apps may correctly prompt an error upon load). If not, let's remove them.

Some widgets may be missing. Please add them. Every single appearance+type combination seemed a little too much, but we should add the ones that are relevant to all (3) OpenRosa form engines.
