Revise user-password.php - Admin folder rename

Update 10-27. Upon further reading about global variables, it seems they only need to be declared when the string replacement is within a function. After testing deletion of the global intended to encompass if/else replacements occurring within a function file outside of a function, the pages appear to 'function' normally. The additional global on the function pages is apparently unnecessary, therefore I am removing them.

Add variable in bl-kernel/boot/init.php that allows User to rename bl-kernel/admin folder. 
User can then define variable in bl-kernel/boot/init.php and change the foldername itself to effect the rename. 

Add global $adminfolder as necessary and replace relevant 'admin' strings with $adminfolder.
Applies to most of the files in bl-kernel/admin/controllers.

Line 53 - Replace Admin string with folder variable:
		Redirect::page($adminfolder, 'users');
Original:   	Redirect::page('admin', 'users');

Line 69 - Replace Admin string with folder variable:
	        Redirect::page($adminfolder, 'users');
Original:   	Redirect::page('admin', 'users')
