Easier dispatchEvent shortcuts mappings

[Bellavene]

Would be perfect if the scripting of dispatchEvent for remapping of physical key's gets a bit more transparent. Right now it is a mess, as I see it.

Um, it has been simplified a bit. When you want to dispatch a keyboard event, it supports such parameters:

1. ctrlKey, metaKey, altKey, and shiftKey: boolean; and if a name exists without a suffix of =false then it is true
2. type: string; may be keydown, keypress and keyup

• 1. when command count is negative, then keydown will be replaced with keyup

4. key: a string which has up to 3 parts joined by a non-word character.

• 1. the 1st part is event.key; the 2nd part is event.keyCode; and the 3rd is event.code
• 2. if there's no 2nd part, while the 1st part is a English letter (a-z), a number (0-9), or Space, Comma, Slash, Minus, then Vimium C will auto calculate a suitable .key, .keyCode and .code

Then you just need to map a key with a command sequence (tree) to dispatch both keydown and keyup, just like https://github.com/gdh1995/vimium-c/wiki/Auto-run-a-tree-of-commands#example , and, in a latest version of Vimium C the %40 can be replaced with / .
