Respect the TRANSFORM_INVALID_GROUP_CHARS setting

[tadeboro]

Up until now, the inventory plugin always replaced invalid characters in group names, which can be a bit surprising when we generate groups on things such as droplet tags. To make things even more confusing, the TRANSFORM_INVALID_GROUP_CHARS configuration option is completely ignored, giving users no way of preserving original names.

This commit replaces the default group name sanitization function with the one that respects the TRANSFORM_INVALID_GROUP_CHARS configuration option.
