Orca string-freeze (and technically gui-freeze) break request

[Joanmarie Diggs <jdiggs igalia com>]

Hey all.

I've just committed a change to Orca master that I'd like to also commit
to Orca's gnome-3-14 branch and include in the approaching release.

Bug: https://bugzilla.gnome.org/show_bug.cgi?id=736595

There's one string (below). In addition, technically this would also
break the GUI freeze. But as a reminder: Orca's GUI is hidden. Only Orca
users will ever find it. There are no screen shots of Orca's GUI. I
myself, along with the help of Orca users, write all of Orca's
documentation because you need to be well-versed in screen readers in
order to write the documentation.

As for why I didn't get this in sooner: I honestly figured this would be
a "preview" feature which users could enable by hand-editing a config
file. But the feature already works far better than expected, and the
bugs are at the level of occasional nits, so I'd like to make this new
feature officially part of Orca 3.14. As for the hand-editing of config
files: Like I stated in the bug, the users who really want this are
those who are brand new to GNU/Linux and just want Orca to behave like
their Windows screen readers. They're not the config-editing types.

Thanks in advance for your consideration of this request.

+# Translators: When presenting the content of a line on a web page, 
Orca by
+# default presents the full line, including any links or form fields on 
that
+# line, in order to reflect the on-screen layout as seen by sighted 
users.
+# Not all users like this presentation, however, and prefer to have 
objects
+# treated as if they were on individual lines, such as is done by 
Windows
+# screen readers, so that unrelated objects (e.g. links in a navbar) 
are not
+# all jumbled together. As a result, this is now configurable. If 
layout mode
+# is enabled, Orca will present the full line as it appears on the 
screen; if
+# it is disabled, Orca will treat each object as if it were on a 
separate line,
+# both for presentation and navigation.
