ProjectExplorer: Introduce dedicated output settings pages

One page for application output, one for build output. The respective
settings are now easier to find, and the general Build & Run settings
page looks more tidy now. We will also be able to link directly to the
respective settings from some button in the output panes in the future.
As a side effect, this patch also introduces a dedicated "word-wrap
output" setting for the compile output pane. It used to share this
setting with the application output pane, which was not obvious and
might not be what the user wants.
