More efficient, and added stability

>Moved checks to new script to avoid duplicate code
>The existence of each script is now checked before it is called
>crashclean.sh now also lists crash files that were unable to be paired
with seeds
>Added more checks for lighttpd.conf
>More verbose about what things are doing
>Removed cap on how much slowdown there can be (seems to keep getting
slower, I previously assumed it would only slow down to a certain point)
