Added SR-EELS_characterisation.ijm:

	This ImageJ macro is used to caracterise the aberrations of an Zeiss in-column energy filter used for SR-EELS.
Changed '*.ij' to '*.ijm'.
Enhanced the rotate images dialog:

- The dialog shows information on the axes.
- An overlay is used to visualize the axes.

Added more comments:

* I added some more block commends and placed all line commends behind the
commented command.
* I use the 2nd Degree Polynomial predefined by ImageJ instead of my own
function.
