The regular expression that Draft's airfoil data importer uses did not allow for lowercase "e" when using scientific notation. This corrects that, and silences Python Developer Mode warnings about deprecated escape sequences by converting most of the regex to use raw strings.
The name of the argument, `projection`, in the old function
is incorrect; it should be `direction`, which was the original
argument's name when this method was split into its own module
(c79f890).
After the reorganization of the Draft Workbench,
the `'DraftText'` objects are now of Proxy.Type `'Text'`.
In the `DraftAnnotation` class the `__setstate__` method
was defined to automatically migrate the Type.
The `Arch SectionPlane` only handles `'Text'` objects. If for
some reason there is still an old `'DraftText'` object
which has not been migrated to the new Type, it won't be found.
This is corrected by adding `'DraftText'` to the list of objects
to process.
