[PATCH] Updated Readme with Github Markdown

[Alex Henrie]

Hello Varunram, and thanks for your interest in contributing to Wine.
The patch you submitted is very unlikely to be accepted because we,
like the Linux kernel and many other projects, optimize our READMEs
for terminal text editors rather than for GitHub. Also, if you submit
any more patches in the future, please be sure to use your real name
and include a Signed-off-by line.
