Title: Issue #19: Generator support

Added support for generator style Graphite functions. These are functions that
can be used in place of a whisper metric to create graphable data. The most
commonly useful generators are `constantLine`, `threshold` and `events`.
`sinFunction`, `timeFunction` and `randomWalkFunction` can be useful for
debugging.

- Extracted generator metadata into its own class.
- Enhanced Graphite_Graph_CallSpec to understand generators.
- Enhanced Graphite_Graph_Series to understand generators.
- Added ini and DSL tests for new functionality.
