Editing comment string in SPE files

[ximeg]

Each SPE file contains 5 lines (each 80 symbols long) of comment strings. It would be nice to add a feature to edit this strings (either in current files, or in all files together).

Idea

• User presses a button ("c" – comment), and a Zenity window appears with 5 lines of current comments. Then the comment can be edited and saved.
• Batch editing. If user presses ("C" = Shift + c), then a list of 5 lines pops up. User can click on the line he wants to alter, then Zenity text input appears (it indicates if something is already stored in this line and if the content is the same across the files). If user clicks ok, then this line is saved in all SPE files in the current folder.

Motivation

Comments are useful thing for saving of experimental parameter of which the spectrometer is not aware (e.g. slit width, laser power, objective type and so on).
