[CORE][ROUTES] Update urlmapper to search dynamic routes before static ones when generating URLs.

Browse Source 
This solves the problem of routes that differ only in having
or not $_GET params. The ones not having params (static) were
being matched first during URL generation.

The way this problem was solved was by separating the $reverse
array in both $reverse_statics and $reverse_dynamics and explicitly
traversing this last one first in the generation function. Note that
maintaining the $reverse array and unshifting dynamic routes to its
head ( and therefore to the front of the static ones ) doesn't work
since even among dynamic routes the order of arrival should be kept.
