Add option to save the datetime as unix timestamp internally
Fixed alignment (4 spaces -> tab)
Reformat code for datetimepicker
Optimize save_post function
Improve autosave
Use WP autosave functionality. Hook to autosave process, modify data sent
New email field
Datalist support for text

Text now supports `datalist` which gives a list of predetermined
autocomplete input responses.  See http://davidwalsh.name/datalist for
more information.
To set up, add an array to the `datalist` argument as follows:
```
'datalist' => array(
'id'=>autocomplete_list',
'options' => array(
'Fruit of the Loom',
'Hanes'
)
)
```

Fixing the map geolocation when having a list of text fields as address_field
normalize_field safe for 'post_type' => array(...)

Adding a default string for complex types, using the "singular_name" only if it's a single post type.  This will correct a small error when an array is used for post_type.

normalize_field safe for 'post_type' => array(...)
Just reformat 'posts' field
Fix #248, #249, also [link](http://www.deluxeblogtips.com/forums/viewtopic.php?id=422)
Shorten checks when saving posts:
- revert check for autosave, using constants. The function `wp_is_post_autosave` is not realiable when current post is Draft
- remove check for user permission, as WP already does that
- remove check for inline-save as verifying nonce is enough

Note: nonce now is verified only, no "permission" nag is displayed when it's invalid. We just return in that case. This won't block other code to execute.
Add filters for text strings so users can change it without using translation.
Maybe better filter names?
Fix notice undefined index for select advanced
Update German translation. Thanks Johann Kratzik.
