Subject: make.bat: Add support for building with ninja.

ninja is an alternative to msbuild designed for fast rebuilds. However there is no IDE support, builds only from the command line.

Comparison between msbuild and ninja for a full build, build time in seconds.

Full Clean Build
msbuild     867.5
Ninja       801.2
Difference  -66.3 (-7.6%)

Minor Change
msbuild      43.0
Ninja        14.9
Difference  -28.1 (-64.4%)

No Changes
msbuild      23.0
Ninja         6.1
Difference  -16.9 (-73.5%)
