* added intermediate ``_read_file`` step dispatching between CSV, ODS
and XLS(X) parsing
- primary dispatch on mime type, secondary on file extension:
+ OS may not provide a relevant mime type if no software locally
installed for the filetype (e.g. Windows sends excel files as
application/octet-stream if excel is not installed, and ODS files as
zip if OpenOffice/LibreOffice isn't installed)
+ applications may re-register extensions to non-standard mimetypes
breaking the dispatcher
So if the mimetype is found trust it, otherwise try with the
filename's extension (if any)
- all readers skip lines with only empty cells in their output
- ODS and XLS content are "CSVified", rows are converted to arrays of
unicode strings
* UI altered to not assume CSV files everywhere, and avoid returning
garbage preview data for non-CSV imports
Various:
* added a ``can_import`` utility function to tests.common, can be used
to skip tests if an optional Python dependency is not installed (but
one would like tests to run if the dependency is available)
* fixed datetime issue in ir_fields
* added converter for monetary fields (iso float)
* spreadsheet don't have integers, twiddling required to ensure integral
values won't be serialized as floats (breaking conversion back to
Python)
* improved some tests by asserting no error is generated (bonus: logs
the error message if there is one, rather than just saying the result
is blown)
* because some systems only provide elderly versions of
XLRD (e.g. current debian stable provides 0.9.2 from April 2013)
- keep using xldate_as_tuple instead of 0.9.3's xldate_as_datetime,
workaround is simple
- check for xlrd.xlsx in case of pre-0.8 XLRD
