Release of v1.0 Beta 11.1

This point release fixes handling of the add-on when running on a user
home directory that contains non-ASCII characters.
Bump to prerelease/preview version

Now 1.0.0-pre.
Provide option to strip specific characters

As a last-minute user request before releasing 1.0.0, this adds support
to blacklist certain characters from being spoken or recorded.

Closes #38.
Cloze handling improvements

Change phrasing of certain labels and options so that they are clearer
for what they are doing, and add a missing option for the note version
of cloze substitution to use the deleted text.
Missing text manipulation options

Really finishes off #38 by adding more options for how to handle these
arbitrary characters, including ellipsizing them and counting them (as
the user reports they are doing in their version).
Do not re-add same sound in non-trim append mode

When running the mass generator, this avoids re-adding the exact same
MP3 to a field if the user decides to turn off the 'remove existing'
checkbox.

Of course, if the user is trying to add a different file, then that will
go through.
Clarify documentation on text configuration

Actually, nested symbols AND overlapping symbols both cause problems are
not supported by the substitution rules.
Missing MP3 file during installation/packaging

Both the install and package script should include the MP3 file from the
source directory.

This fix must be backported via a cherry-pick to the pre/v1.0.0 branch.

(cherry picked from commit 978d5a4fb4b9cfeca95b0f6a5335538a0422308d)
Disable horizontal scrollbar in updater
