I did not wanted to change cache_tms since TMS is a standard, so I've added a new cache source that is based on your idea and way more flexible than the existing cache_tms.

Example:
  - type: cache_tiles
    url: http://localhost:8080/tile?x=%(x)s&y=%(y)s&z=%(z)s&format=%(format)s
    origin: ``nw``

The new cache_tiles accepts the following keys:
``x``, ``y``, ``z``
  The tile coordinate.
``format``
  The format of the tile.
``quadkey``
  Quadkey for the tile as described in http://msdn.microsoft.com/en-us/library/bb259689.aspx
``tc_path``
  TileCache path like ``09/000/000/264/000/000/345``. Note that it does not contain any format
  extension.

This should add support for most tile servers out there. Let me know if I missed some obscure format :)

The change will be included in 0.8.3:
