Make it compile again on 32/64-bit Windows

* Mozart won't compile on 32-bit Windows because it requires lot of
contiguous memory and 32-bit max virtual memory is too small, so reduced
its max memory usage to 512MB
* The --eval of emacs command seems to do a mess when compiling. The -L paremeter do the same thing more simply.
* Tests couldn't be run because ozemulator is ozengine on Windows
* Updated CMakeLists to support x64 compilation on Windows
* Updated platform detection function call to allow 64bit Windows to be recognized
Updated Windows README

Nuwen's MinGW does not support 32-bit anymore, clang 3.4 does not seem to work
with MinGW and Boost...
Added icon for Mozart launcher on Windows

Just to give the shortcuts a better look...
Package icons and dependencies for Linux

* Added icons and desktop shortcuts for Linux
* Added lines for dependencies (may be modified by the packager) for DEB and
RPM packages
Added Inno Setup packaging method

* Retrieved ModifyPath.iss from Mozart 1 repo and updated it
* Added Inno Setup scripts with batch file to check Tcl version
* Modified CMakeLists to compute Inno Setup configuration
* Added make installer target on Windows to launch the process
* Updated Windows README to include setup making notice
