Fix for PATH_ADDON encoding

This checks the system encoding and decodes the current working
directory into a unicode string based on that, fixing start-up crashes
when the add-on tries to read the configuration file.
Use system temporary directory

This has been put in as a fix for Windows users who cannot send
non-ASCII paths via CLI interfaces, which affects things like
transcoding. By using the system temporary directory, we can later, in
Python, move the file to its correct place.
Add note regarding sqlite

Adds a note regarding the need for the getfilesystemencoding call.
Bump version number

With this quick fix applied to the stable branch, this causes a minor
point release.
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.
