pattern aliases

[HiveTraum]

✋Reopened #598 because i noticed that the project came to life

This feature introduces ability to register aliases for some often used regular expressions.

For example path as this: /{category:[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-4[a-fA-F0-9]{3}-[8|9|aA|bB][a-fA-F0-9]{3}-[a-fA-F0-9]{12}}/{product:[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-4[a-fA-F0-9]{3}-[8|9|aA|bB][a-fA-F0-9]{3}-[a-fA-F0-9]{12}} can be transformed into this /{category:uuid}/{product:uuid}

You need just use register it

router := NewRouter()
router.RegisterPattern("uuid", "[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-4[a-fA-F0-9]{3}-[8|9|aA|bB][a-fA-F0-9]{3}-[a-fA-F0-9]{12}")
router.Path("/{category:uuid}")
router.Path("/{product:uuid}")
router.Path("/{order:uuid}")
router.Path("/{user:uuid}")

1. New method RegisterPattern on Route struct
2. New method RegisterPattern on Router struct
