* This is a built-in function of iOS Safari that didn't work because the
page content was inside absolutely-positioned, scrollable divs.
* The fix is to stop using absolute positioning on `.page-wrapper` and
`.page`, so that the content uses static positioning and flows
naturally down the page.
* Consequently, `.sidebar` and `.nav-chapter` now have to use `position:
fixed` in order to be positioned relative to the viewport.
* This fix also enables Safari's built-in behavior of automatically
hiding the top and bottom toolbars when scrolling down the page.
List of system fonts (R, I, B means roman, italic and bold. Ubuntu probably comes with more fonts, but I couldn't find a list to confirm.):
```txt
Windows
----------
Consolas R RI B BI
Courier R
Courier New R RI B BI
Lucida Console R
Mac
----------
Andale Mono R
Courier R RI B BI
Courier New R RI B BI
Menlo R RI B BI
Monaco R
Ubuntu
----------
Ubuntu Mono R RI B BI
DejaVu Sans Mono R RI B BI
```
```css
font-family: Consolas, "Ubuntu Mono", Menlo, "DejaVu Sans Mono", monospace, monospace;
```
Consolas and Ubuntu are professionally designed fonts ([Lucas de Groot][1] and [Dalton Maag][2]), with true, calligraphic italic, so they go at the top of the stack.
Menlo is [based on DejaVu Sans Mono][3], the only difference being a few tweaked glyphs, so DejaVu serves as a fallback for it.
As for Courier New, other than being unreadably spindly, it's the default monospaced font in all browsers, so there's no need to include it in the stack.
The `monospace, monospace;` declaration is, by now, [a standard hack][4] that overrides some browsers' behaviour of defaulting the `monospace` elements to smaller font size. Without it, any relative font size you apply to them will be calculated from that reduced size (seems to be 13 px in all browsers).

The div is now inserted after the <i>, the text color has also been changed to the foreground color and the "(default)" text that indicates the default theme is now grey to contrast with the theme name
Fixes#97
Added basic formatting for tables so that they have some padding and are aligned in the center of the page.
I did not add color or borders because I am not sure how tables should look like.
A lot of people in IntermezzOS want asides, blockquotes are probably the easiest way to do that. I have thus styled blockquotes for all the color themes.
