Turn latitude and longitude into integer micro-degree values

This actually makes us internally use 'micro-degrees' for latitude and
longitude, and we never turn them into floating point either at parse
time or save time.

That said, the Uemis downloader internally does still use atof() when
converting things, which is likely a bug (locale issues and all that),
but I'll ask Dirk to check it out.
