Optimized BrowserBox

* Introduced a LayoutContext that conveniently allows for relayouting
  all rows, or just a single one when it is added. BrowserBox::addRow
  no longer relayouts all the rows.

* BrowserLink and LinePart are now merged into a new TextRow struct,
  so they can be conveniently dropped when the row limit has been
  reached.

* Removed "opaque" option, which was enabled by default but disabled
  for all BrowserBox instances.

* Removed "always update" option, and instead start delaying relayouting
  automatically when there are a lot of rows (> 100 currently).

* Update window now also has text wrapping enabled.

Closes #50
