Purpose of this patch is to get rid of kmm_csvimport_static.
Advantages:
- no bulky kmm_csvimport_static,
- test cases can use kmm_csvimport_core directly,
- CSV importer is even more separate from CSV wizard than before,
- webpricequote update now can link only to CSV importer without
wizard,
- webpricequote and CSV Wizard use the same binary (i.e. shared
library),
- kmymoney binary + shared library + plugin library is about 15 MB
smaller, than before.
