Upgrade ackmate_ack?

[inkytonik]

Is there any chance of upgrading the version of ack used in the plugin to a more recent version? 1.96 seems to be the current version and it has some options which I'd like to use that the ackmate version (1.92) doesn't have. E.g., --color-lineno. Having an incompatibility between the ackmate version and the command-line one means that a single .ackrc can't be used.
