Helper trait for Grid layout.

This helper enables using the GTK Grid for laying out widgets in a window. For example, the following snippet specifies a layout that will render to look something like this:

   +--------------------------------------------------+
   |         +-------------------------------------+  |
   | Label1: | Text input                          |  |
   |         +-------------------------------------+  |
   |         +-------------------------------------+  |
   | Label2: | Another bit of text                 |  |
   |         +-------------------------------------+  |
   |  +--------------------------------------------+  |
   |  |                                            |  |
   |  |                                            |  |
   |  |                                            |  |
   |  |              More stuff here               |  |
   |  |                                            |  |
   |  |                                            |  |
   |  |                                            |  |
   |  |                                            |  |
   |  +--------------------------------------------+  |
   |                                   +-----------+  |
   |                                   | A Button  |  |
   |                                   +-----------+  |
   +--------------------------------------------------+

gtk! {
    <Grid row_spacing=10 column_spacing=10>

      // --- Row 0 ---

      // Widgets are placed by default in the top left corner, so this
      // label does not need any additional annotation.
      <Label label="Label1:" halign=Align::End />

      // This text entry is being moved to column 2. We don't specify
      // the row because, again, by default it is placed in the first row
      // which is what we want.
      <Entry Grid::left=1 hexpand=true />

      // --- Row 1 ---

      // Leave the column at its default of 0 and set the row to 1.
      <Label label="Label2:" Grid::top=1 halign=Align::End />

      // Place this text entry in row 1 and column 1.
      <Entry Grid::left=1 Grid::top=1 hexpand=true />

      // --- Row 2 ---

      // We want the following widget to span the width of the grid and
      // also consume excess vertical space.
      <ScrolledWindow Grid::top=2 Grid::width=2 hexpand=true vexpand=true>
        <ListBox />
      </ScrolledWindow>

      // --- Row 3 ---

      // We leave the first row unoccupied and only have a button in the second
      // column.
      <Button label="A Button" Grid::left=1 Grid::top=3 hexpand=false halign=Align::End />

    </Grid>
