Community and Support imporvements

[Nekroze]

To ease contributions Gandalf should have a CONTRIBUTING.md file to explain any guide lines, this issue is to discuss and formulate what should be in that document as it too should be a community effort.

[patrickgordon]

a proposed workflow would be useful.
e.g. fork, change code, PR

[Nekroze]

I would suggest creating a new branch post fork but that is good @patrickgordon

[Nekroze]

@patrickgordon seems we have just described github flow together

[Nekroze]

seems like it would also be worth mentioning some best practice recommendations for maintaining a fork on github similar to what is outlined here https://gist.github.com/yannvery/497ccbf26e4a71e8ad50 although I think the merge could be done better

[Nekroze]

would like all merging of PR's to be done with the Rebase and Merge option
