Improved styling of views of Fancy Menu a little

[tsujan]

• CategoryView and AppView can be styled independently.
• If you don't add a background for CategoryView, it'll have the background of LXQtFancyMenuWindow (previously it did only without stylesheets).
• The patch also enforces the stylesheet background color of LXQtFancyMenuWindow (if any) on widget styles that try to override it (like Kvantum).

I can't get to work

 #FancyMenu AppView {
    background-color: red;
}

Same for CategoryView. Am I missing something? AppView has alwayspalette(view) background.

EDIT: I missed # as it's an object not a class.

 #FancyMenu #AppView {
   ....

There is an issue with stying the 2 scrollbar, atm, this white square.

It isn't related to this PR. You could remove it by using this:

#FancyMenu QAbstractScrollArea::corner {
    background: transparent;
}

I found it only by chance ;) Before merging this PR, I wait for you to try the above trick and let me know if it works.

BTW, I also found a way to resize the widget such that CategoryView doesn't have any vertical or horizontal scrollbar with any font size (as long as it can be fit into the screen, of course). I'll make another PR after this one is merged.

I know - this snippet works, nice! For some reason the square was only visible in CategoryView but not with "All Applications where they are 2 scrollbars too.

That's fine, in AppView both scrollbars can appear, with long names and/or in "All Applications"

Yes. It'll be only for CategoryView.
