Bump to hotfix version

Switches VERSION to 1.2.1-pre.
Display correct noun for SAPI voice count

With this, if the user only has one voice installed, AwesomeTTS will
report it as "1 voice" instead of "1 voices".
Router hashing: skip conversion if already string

If a value is already a string, do not try to pass it through the str()
function (since this will fail if the given value is a unicode string).
Encode SAPI voices in JScript gateway

Depending on the version of the Windows, the unicode characters can get
mangled, which might cause failures on the Python side.
Accept SAPI 5 voices named without diacritics

If the user uses a "voice" attribute for a SAPI voice that is missing
its diacritic, figure it out and find the correct voice name.
Release of v1.2.1

Fixes some SAPI 5 problems with IVONA voices.

(Merge branch 'pre/v1.2.1' into stable)
