Ubuntu instructions needs to be updated

[bosmanoglu]

Hi,

I just installed mapready on ubuntu 16.04 and the instructions provided in the readme, needs to change slightly. The commands on my system were:

sudo apt-get install git bison flex g++ gcc libgdal-dev libgtk2.0-dev libglade2-dev libgsl-dev libproj-dev libtiff-dev libgeotiff-dev shapelib libshp-dev libcunit1-dev

And note the "/" after github.com in the next line. The readme has a ":".

git clone git@github.com/asfadmin/ASF_MapReady.git ASF_MapReady

The rest of the commands work as expected.

best,
batu.
