Note di rilascio per la versione 0.8.23.1

This is a stability release.

Fixes:

• Fixed real-world crash occurring under certain conditions at application startup, which prevented 15 users to try product.
• Fixed real-world crash occurred to a handful of users who updated from a previous version and had a .net 4.0 "client profile", or new installation with a .net 4.0 client profile; the crash was experienced when trying to load an existing project or to start a crawling session. This is consequence of trying to support multiple runtimes, it all went "almost" smooth... sorry guys. Well, now it's hopefully fixed.
• Fixed robots.txt parsing issues, where in some cases a bot-specific options group was not considered correctly and access to the URL resulted denied.
