Policy for removing inactive developers.

Currently inactive developers tend to keep commit access, while this hasn't been an issue so far, developers move on and if they haven't committed in a very long time, we could periodically remove them.

Since there is some security issues (if their account becomes compromised for example).

This can apply to:

• Blender's git repository.
• Blender's git add-on repository.
• Blender's svn documentation repository.

Others repositories could be included, this is just an initial list.

Proposal:

• Periodic list developers which haven't committed anything for a long time (suggest 2-3 years, could be done each release).
• Mail the bf-committers mailing list with a list of these developers, allowing them to request they keep commit access (suggest one month).

This way we're not over-eager in removing developers, and anyone who intends to contribute can request their access be kept.
