The changes enclosed fixe various issues in the previous implementation. It breaks webdav though (wait for next commit to get it back).

Standalone "External Documents" may be created by specifying

of documents into an ERP5 Site.
ContributionTool is configured in portal_types in
such way that it can store Text, Spreadsheet, PDF, etc.
ContributionTool needs to be configured in portal_types (allowed contents) so
that it can store Text, Spreadsheet, PDF, etc.
The method to use is portal_contributions.newContent, which should receive
either a portal type or a file name from which type can be derived or a file from which
content type can be derived, otherwise it will fail.
The main method of ContributionTool is newContent. This method can
be provided various parameters from which the portal type and document
metadata can be derived.
Configuration Scripts:
- ContributionTool_getPropertyDictFromFileName: receives file name and a
dict derived from filename by regular expression, and does any necesary
operations (e.g. mapping document type id onto a real portal_type).
