Rockbox Utility currently exposes SAPI5 voice speed but not the SAPI
voice volume. The encoder volume setting is applied after synthesis, so
it cannot prevent clipping or distortion already present in the
generated wave file.
This patch adds a Volume control to the SAPI5 TTS configuration. The
value is passed to the standard SpVoice.Volume property before
synthesis.

The existing code treated any ready-read notification from cscript as
proof that synthesis had completed. The SAPI script can emit other
output, so the Utility could check for the wave file before the explicit
SYNC reply and report that the output file did not exist.
The script also used global "On Error Resume Next" without reporting
errors from SpFileStream.Open(), SpVoice.Speak(), or
SpFileStream.Close(). Several waits had no timeout, allowing the GUI
thread to remain blocked indefinitely.
The changes:
* reports SAPI COM errors to Rockbox Utility;
* verifies that SAPI actually created the requested wave file;
* waits for the explicit SYNC reply instead of any process output;
* applies finite timeouts to vendor queries, synthesis, and shutdown;
* terminates a stuck private cscript process safely;
* restarts cscript and retries the current string up to three times when a
third-party SAPI engine stops responding during a long generation run.

MSSP is accessible via vbs by simply changing the object to be used (both
SAPI5 and MSSP use the ISpVoice COM interface). Add command line parameter to
sapi_voice.vbs to switch the COM object used, and add the necessary
implementation of the SAPI class to Rockbox Utility.
Important: you will need to install the Speech Runtime separately and install
the version matching the bitsize of Rockbox Utility. I.e. you will need to
install the x86 version even on a x64 machine (unless you build a 64bit binary
of Rockbox Utility).

The currently used comma for separating voices for the /listvoices command is
used by Speech Platform based voices. Change the character to a semicolon
which isn't used by voices.

Unset svn:eol-style=CRLF on this vbs file and convert it to LF line endings.
VBScript is perfectly happy to run with LFs and this removes the last
inconsistent line ending in our repo :)

Extend sapi_voice.vbs with slovak (FS#10904). Additionally add it to the list
of supported languages in Rockbox Utility and fix the country code used for
slovenscina (by myself).
