[Feature] Improve options Main menu location

[Hofknecht]

Thank you Tom for reporting:

There seems to be 3 options that control the location that the Main menu will appear:

a. Bottom right 
b. Bottom left 
c. Mouse location (Above Taskbar icon)

Since only one of these option can be used at a time I thought being able to check more than one might be confusing. So I thought radio buttons could be less confusing. For example, the options layout could appear something like this:

Main menu appears at:
===============

● Bottom right
○ Bottom left
○ Above taskbar icon

=>
(a problem is we do not know the taskbar icon location)

-radio buttons are good
-option c might be a specific configurable location. The user might need to set it by two textboxes x and y. Maybe addionally, it would be nice if the user can drag and drop the main menu by title to this position.

-or we can appear at mouse location but not when user presses hotkey, maybe then appear at location where last time mouse opened the menu, we have exactly this behavior when you check these 3 options (then you can also place with hotkey and first start wherever you want to have it)

at the moment i think this is how it could be done:

Main menu appears at
● Bottom right
○ Bottom left
○ Mouse location (Above Taskbar icon)

☐ refresh location each time

-'refresh location each time' only enabled when cache menu activate
-we will move 'Round corners' into tabpage 'Customize' together into a groupbox with 'always dark mode' maybe name it appearance
-rename Size and location -> size
