Rewrite CSV import

[epruesse]

• always import all columns (or rows)
• target field names will be
  • either f1 … fN
  • or auto-generated from content of column-headers (or row headers)
• if column-headers get used
  • auto-select first non-empty row as header or
  • specify a specific row
• define column(s) used to identify species
  (i.e. containing something unique like shortname, acc)
• optionally use FTS
  • to provide selection, renaming and post-processing of fields
  • does also provide handling for existing fields (needs #814)
  • w/o FTS ⇒ hardcode behavior when target field exists
    (abort with error or overwrite?)
• store configurations
• show preview of selectable row (similar to preview in importer)
  • shall auto-select the corresponding species
    ⇒ species-info will show unmodified state (nice for comparing)

It might make sense to have a look at openoffice/excel and design the interface to resemble their CSV import windows.
