Move Guillotine tool to a different position in menus (and rename it)
Description of the feature
The Guillotine tool is currently located in Image --> Transform menu together with Flip and Rotate tools. This position doesn't make any sense, because Guillotine is more related to Crop tools or Guide tools and it would be better to move the Guillotine tool to one of these groups (Crop tools preferably - that's the place where I would look for it).
Also, please consider renaming the tool. The name 'Guillotine' doesn't say much about the tool. 'Slice Using Guides' would be more appropriate and understandable.
