Be X.5 only / use own queue for web archive downloading
Update Spotlight Importer Project for X.5
Additional warnings & solutions for warnings 
add missing superclass call
Add Timeout condition to downloads
Use NSString instead of NSURL

NSURL cannot be used in property lists
simplify WebKit loading
different caching approach

(doesn't really seem to help)
unset delegates before closing the WebView

otherwise it seems to send fail messages which we don't want to receive when in the timeout situation
more/improved logging of delegate messages
add note on different ways of creating webarchives
rearrange files in project
hold option key art launch time to see settings window
use correct version string
fix typo in selector name
correct icon file name extension for pinboard
add -timeout method name to @interface
bump alpha version to 0.6a2
delay performing the switch to the next queue item

otherwise it is executed as a child of some WebKit callback and initiates a new download which may be the reason for the occasional crashes I was seeing.

Many thanks to Mike Abdullah for the advice leading to this.
