libtheora 1.1.1 release

All,

I've made a follow up release in the 1.1.x series. This fixes some
issues reported with last week's 1.1.0 release, and is mostly of
interest to those building under MSVC.

Changes:

* Fix an error in the MSVC inline assembly, the "pink blocks" problem.
* Don't use the ebx register in the MSVC asm because it's used by the
compiler in some optimization modes.
* Include the file encoder_disabled.c so --disable-encode works again
in the autoconf build for those who don't want to just link with
libtheoradec.
* MSVC project files now use the default dynamic runtime library.
* Namespace some local variables to avoid a conflict on WinCE.
* Include pkg,m4 and replace libtool so autogen.sh is more likely to
work in release packages.
* Remove 'beta' from the README.
