Various fixes

[ziima]

Fix several bugs:

• Set cache state properly (especially disabled)
• Prevent TypeError when simulating GPS.
• Prevent ImportError when using hildon GUI.
• Prevent connection errors when connecting to geocaching.com using bugged versions of OpenSSL.

I have added two other commits.

First one continues with download if there is error in cache page parsing.
Second adds and refactors cache types. It also contains some additional refactoring which should be finished.

Cleaned up the rest of imports. It caused some import bug on N900.

After all these comments on single commits or lines, I'd first like to thank you for the patches. I will try to use as much as possible. However, it would be easier if the refactoring things would be separated from the changes in functionality.

Ad 1) The download of overview is quite a big method and bit confusing, it should be worth splitting it into several ones. If you think that these flags are the same or similar enough, we should merge them.
Ad 2) That is bad :( But the parsing of date format is preference dependent as well, is it not? I checked the HTML, but I did not found no way to differentiate between disabled and archived. Only language-independent way to resolve this from cache page is to download all (!) the logs.
Ad 3) I applied this patch to my N900 and it looks good so far :)
Ad 4) I my experience, using namespace is fairly common in well behaved python 2 libraries. You might encounter serious problems when you do not differentiate between your imports and import from other libraries. Especially for common names like utils and gui. You might also run into troubles with modules copied from other sources, like threadpool and pyfo. You can check the projects I poked my nose in :)
It would be also nice to add a shell script(s) that starts AGTL, so sys.path is not changed on the run. But I did not know how you will react to my refactoring, so I did not do it.
Ad 5) Yes, I am sorry for that. At first I just wanted to fix the bugs I found, but I fell into it.
