#11 Allow untrusted operation

[Paul Lamere]

FreeTTS should be packaged such that a WebStart or
applet can use FreeTTS in a sandbox. This would allow
application writers to use FreeTTS without having to
sign the jar file. Currently the only reason FreeTTS
needs to be signed is that the voice manager looks for
voices in a set of directories. There should be a way
for an application to say: "only load voices as
resources" that would restrict FreeTTS to searching
just in the jar webstart jar files.

Currently, FreeTTS can be used in WebStart apps if the
jars are signed. This is unacceptable for some
applications.
