Work in progress: version 1.0.6

The next release of the MyImouto is, as usual, taking a while because, as usual, I'm doing huge changes to the code. But this time, to the framework.

Some things that will come in 1.0.6:

• Improved database queries for post#index.*
• Enabled some caching that were missing for complex queries.
• Framework now supports Memcached for caching (much faster).
• Improved framework overall.

And a lot more... fixes and additions and stuff.

* With 200k rows in the posts table, post#index would take up to 30-40 seconds to load. After these changes, it now takes up to 3 seconds or less. Which is still slow but a lot better than before anyway.
