Need to update grunt bump #830

[BenjaminNeilDavis]

Created a replace task in grunt. Moved a copy of details and readme to src directory. I replaced all referenced to version number with variable that the tasks replaces with current version.
Added replace task to the end of "dist" task. Can be moved if there is a preference.

Is there anyway to do this without duplicating the markdown files in a src folder? Possibly using command line vars.

Also, could we put this in the release task? Maintainers will be using the dist task to update master without wanting to officially update the version.

Not sure about the markdown files but will look into it. I will also move the task.

I changed the way I replaced the version by looking for creating a regex for the version in the two files. Now it just overwrites the file instead of copying from template.

Nice work, this will make my life easier.
