GitHub processing script setup, clone added

mattpass · mattpass · commit 77559afe600d · 2014-06-03T09:30:55.000+01:00
Detect if SSL capabilities are available and if not, inform user what
they need to do.
On cloning, establish local and remote paths and if our root is in the
local list, establish the target, zipURL and zipFile path &amp; name
Get the zip file over file_get_contents if possible, otherwise cURL.
Then unpack the zip into our local folder. The first entry will be the
folder inside of the zip, so we get the $dirName of that only to use,
this is removed from subsequent file paths
When done, remove the zip file and refresh the file manager to show the
files
