[WIP] Menu widget

[Kaiden42]

First draft of a Menu widget.

Open TODOs:

• [x] Disable entries. This could be achieved by changing Message to Optional<Message>.
• [x] Toggle-able entries. This could be achieved by adding a Entry::Toggle or something to Entry.
• [x] Cool looking separators between the entries.
• [x] Bouncing on the edge of the window or else the menu is cut off.
• [ ] ~Add some internal scrollable if the list of entries is to high for the window.~ This seems to be realy hacky to implement. Nevertheless it would require for the scrollable::State to be hashable and maybe to fix this first.
• [ ] Maybe a cooler default style. Some suggestions?
• [ ] Add some way of keyboard control. In common, the Alt + [First character of section label] combination is used to pop up the content of the specific section. This would require to change the Text label of the Section to a normal String (or &str) to be able to know the first character of the label.

This is very nice! I was thinking of making something like this for my chat app since using a PickList as a menu was hacky, but looks like you were faster :P

It seems we can use anything that can Into<Element<_>> for menu entries which is appreciated. Something that would be nice is methods on Menu that would help with prototyping, eg. perhaps a method that takes an array of strings for easier creation of text-only Menus etc.

Hmm for styling lets just stick with a workable default. Also scroll-able stuff should be fixed to render properly since a few versions back. a few keyboard controls would be nice probably can try to help implement them later. Also the pure edition might also fix the state hashing requirements for the scrollbars.

@genusistimelord For now, I would prefer to wait for the support of the real system menus (iced#1047, iced#114). What do you say?

yeah thats fine. was more or less stating how the current changes in iced have already changed some of the requirements.

I am closing this since menu now exists. Decided to allow it since this cant be supported fully in other ways. we might not see its support for a long time if any.
