Include file exclusions don't work

Issue Summary

I noticed that the exclusions were not working on this string:
sites/all/modules/custom/*/node.*.inc

A dsm() of the $exclusions variable showed that it was being converted to this regex:
sites\/all\/modules\/custom\/\.*\/node\.\.*\.inc

node.*.inc should end up as node\..*\.inc, but the . in .* is getting escaped. Looks like this is caused by the order of string replacement in prepping the regex.

This patch moves the * replacement to the end of the str_replace() operation and fixes it for me.
