scripts/release.pl: remove slicer-specific deployment functionality.

Nobody is using release.pl for deploying tarballs
automatically anymore.

Our builder bots were manually sed'ing out these
parts of the code before running release.pl, so by
dropping it completely, we can clean up their build
scripts a bit.
scripts/mkini-win32.bat: use ',' as substitution delimiter; also fix regexp.

Using '!' as the delimiter has an unfortunate clash with cmd.exe's
delayed expansion feature. When delayed expansion is enabled, the
substitution would fail with a syntax error because cmd.exe had
mangled the substitution string before passing it to Perl.

This commit also fixes the regular expression to match the one
found in mkini.sh.
scripts: set +x bit for the files people are expected to run.
winpaths_static.pri: remove executable bit.
scripts: remove old Ermine build scripts.

We have an updated variant in Jenkins which builds on CentOS instead
of Ubuntu.
scripts: remove unused svn2cl scripts.
AudioOutput: add an 'attenuate others' option for priority speakers.
TextToSpeech_macx: reimplement using NSSpeechSynthesizer.

Fixes Text-to-Speech not working on Mavericks and
avoids several deprecated API calls.
TextToSpeech_macx: fix 10.4 compatibility.

Remove @property and @synthesize to make the
code work on 10.4.

Also import AppKit.h to fix the build when
building without PCH support.
README.static.osx: remove Linux references.
TextToSpeech_macx: selectively conform to NSSpeechSynthesizerDelegate protocol.

MUSpeechSynthesizerPrivateHelper currently conforms to the
NSSpeechSynthesizerDelegate protocol, which was an informal
protocol prior to 10.6.

Our legacy universal builds currently use the ancient 10.5 SDK
and does not know of the NSSpeechSynthesizerDelegate protocol,
which was first introduced in the 10.6 SDK. Because of that, the
legacy universal build is currently broken.

To fix it, we change the code to only adhere to
NSSpeechSynthesizerDelegate via a class extension. This class
extension is only exposed to non-universal builds using the 10.6
SDK (or greater).

Merge v1.2.5 into master.

This brings us back to our usual snapshot
versioning scheme.
g15helper: update G15 SDK paths for OS X.

The g15helper program is currently coded against Logitech's
legacy G15 SDK. Logitech's newer SDK, which is the only one
shipped in their newer versions of Logitech Gaming Software,
is not compatible.

For OS X, the legacy SDK is still available for download
if you download the version of LGS (GamePanel 3.x) that
supports OS X 10.4 through 10.6. However, the SDK shipped
in this version of their software uses slightly different
paths than we expect.

This commit changes the paths to make sense with the SDK
shipped with the GamePanel 3.x software.
