IPerson.createPPA's only accepts a single line description on webservice

[Robert Bruce Park]

Just saw this error calling createPPA() in lplib:

Calling .strip() on the string passed to description fixes the issue. Would be nice if LP was more robust against whitespace in submitted values. Either preserving it without exploding, or if it really can't handle it for some reason, stripping it itself rather than exploding.

IPerson.createPPA's description field is a TextLine, but it should be Text.

Ideally it would use copy_field, but registry shouldn't import soyuz.
