Remove requirement for git for installation

[rjmunro]

It looks like this requires a command line git before it can be installed because when I try to install this in a container on https://hyperdev.com/, I get the following in error logs:

GitKit is still using a fork of dissolve, waiting for deoxxa/dissolve#20 to be merged.

Thanks.

I had assumed it wanted it because it's a git related project not because npm needs it to install a dependency, but now I realise this is more hyperdev's problem than gitkits - it applies to any non-npm dependency.

I've reported the issue on their support, and they've said they'll look at it:
