We don't bother keeping all files in memory as there
can be several, and we don't need them all. This just
adds a Close() method that can be used to ensure the
temporary files are removed.

format: implement support for evaluating spreadsheet number formatting
...
This adds support for extracting a cell's formatted value according to
the number format applied to the cell. To do this we need to implement
a parser for Excel style format strings and support formatting numbers
according to that style.
This also enhances the General formatting to be much closer to what
Excel normally does. There are likely still a few corner cases where
Excel and gooxml differ, but hopefully not too many.
