Change git URL

[sprowell]

Did not see this elsewhere, sorry if missed.

Two suggestions.

(1) I would suggest changing the URL used in the documentation and in the install.sh script to use https instead of git. This is more likely to work well through firewalls and the like. For example, git fails with the following from my work machine.

Cloning into '_bootstrap'...
fatal: unable to connect to github.com:
github.com[0: 192.30.253.112]: errno=Connection refused
github.com[1: 192.30.253.113]: errno=Connection refused

(2) Pursuant to the above, and way less important, check the output of the git command before moving on. Otherwise you end with the following error.

install.sh: line 15: cd: _bootstrap: No such file or directory

So, to summarize, I recommend replacing this line:

git clone  --recursive git://github.com/LuaDist/bootstrap.git _bootstrap

with this line:

git clone  --recursive https://github.com/LuaDist/bootstrap.git _bootstrap || exit 1

Added: It wasn't clear, but I think this change should be made throughout the scripts, so also in config.lua, for instance.
