+solver.

+Extract button will just extract stars from image and it will show their count, HFR and eccentricity. This action doesn't need index files.
+Solve button will try to find coordinates of images. Abort button will stop extraction or solving. Update FITS header will update FITS fits keywords
+with found solution.
