More indexer work:
- all String properties may now be indexed too. Currently there's a bit of
"issue" specific code in the actual searching which needs to be
addressed. In a nutshell:
+ pass 'indexme="yes"' as a String() property initialisation arg, eg:
file = FileClass(db, "file", name=String(), type=String(),
comment=String(indexme="yes"))
+ the comment will then be indexed and be searchable, with the results
related back to the issue that the file is linked to
- as a result of this work, the FileClass has a default MIME type that may
be overridden in a subclass, or by the use of a "type" property as is
done in the default templates.
- the regeneration of the indexes (if necessary) is done once the schema is
set up in the dbinit.
