Add document how to compile dragonwell8 from source code

for example, at debian/ubuntu

sudo apt-get install libx11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev libcups2-dev libfreetype6-dev libasound2-dev
chmod +x configure
./configure --prefix=/usr/local --with-freetype-include=/usr/include/freetype2 --with-freetype-lib=/usr/lib/x86_64-linux-gnu

make 
sudo make install

Working in progress. Need time for both process and code. Please stay tuned, thanks!
