make tool bar full width using a layout

[PGimenez]

The issue with the toolbar is that it needs to be inside a q-headerand inside a q-layout. We do this in the component gallery with this code

StippleUI.layout(style="margin:auto;max-width:800px",
    [
        quasar(:header, style="background:darkblue", toolbar(
            [
            btn(; dense=true, flat=true, round=true, icon="menu", @click("left_drawer_open = !left_drawer_open")),
            toolbartitle("Genie Component Gallery")
        ],
        ),
        ),
...

To use this, I've defined a page_layout function in layout.jl and used it in every _uipage. This works, but isn't the best option and needs some improvements.

Ideally, you'd define the layout like
layout.jl:

StippleUI.layout(style="margin:auto;max-width:800px",
    [
        quasar(:header, style="background:darkblue", toolbar(
            [
            btn(; dense=true, flat=true, round=true, icon="menu", @click("left_drawer_open = !left_drawer_open")),
            toolbartitle("Genie Component Gallery")
        ],
        ),
        ),
        page(model, partial=true, [@yield]) <--- this injects the page's content
])
...

and then use the layout in the page definition as @page("/home", "home_ui.jl", layout="layout.jl", model = HOME). That way you don't have to include("layout.jl")and then call page_layoutin every page.

However, for some reason if the layout.jl has a StippleUI.layout component then the resulting page looks weird, as if no styles were applied. I'll need to figure out how to fix this in a new issue.

I've opened an issue about this here

GenieFramework/Stipple.jl#281

In the meanwhile, this PR implements a workaround to use layouts with Quasar components.

I just realised that when each page is first loaded, the app throws an error about page_layoutnot existing....will have to find another way to do this =(

Weirdly enough, it only fails on the first load of the page. If you refresh it, the code works...

Adding @eval did the trick for some reason.
