GUI for CSV import

This patch implements GUI for importing CSV log files. One is able to
configure what columns contain time, depth and temperature fields.
Pre-configured log applications currently included are ADP log viewer
and XP5. (Both of these use actually tab as separator, so the field
separator currently hard-coded.)
