- added a new queue 'noload' which can be filled with urls where it is already known that the content cannot be loaded. This may be because there is no parser available or the file is too big
- the noload queue is emptied with the parser process which indexes the file names only
- the 'start from file' functionality now also reads from ftp crawler

- better control to the cache by using combined request-header and content access methods
- refactoring of many classes to comply to this new access method
- make shure that the cache is always written if something was loaded
- some redesign of the process how http response results are feeded into the new indexing queue
- introduction of a cache read policy:
* never use the cache
* use the cache if entry exist
* use the cache if the proxy freshness rule confirmes
* use only the cache and go never online
- added configuration options for the crawl profiles to use the new cache policies. There is not yet a input during crawl start to set the policy but this will be added in another step.
- set the default policies for the existing crawl profiles. If you want them to appear in your default profiles you must delete the crawl profiles database; othervise the policy is 'proxy freshness rule'
- enhanced some cache access methods in such a way that unnecessary retrievals are omitted (i.e. for size computation). That should reduce some IO but also a lot of CPU computation because sizes were computed after decompression of content after retrieval of the content from the disc.
