i18n fixes and italian translation

[keul]

Mainly i18n changes:

• italian translation
• i18ndude script added
• removed needs of manual translations
• removed german messages from templated and needs of "en" translation folder

Other changes:

• re-enabled the "view" tab (not sure why it was disabled)
• Now use DataGridField 1.9+, with new features like required column value, column description. I was also planning to require 1.9.1+ where DateColumn has been added but there's no real change in the UI right now (PR Datecolumn collective/Products.DataGridField#15 is not merged)

Hey, thanks for your work!

It looks good, I'll update the German translations after merging.

Just a note on the runi18ndude.sh script:
We usually have development.cfg creating a bin/i18n-build script.
The development.cfg was missing, I've added it to master.
So I'll remove your script after merging so that we can follow our company policy 😉

I also discovered that the required in the DataGridField is not very handy in combination with auto_insert=True: an empty line is always automatically inserted, leading to a validation error:

I'll remove the auto_insert flag.

I've released ftw.poodle = 1.5.0 with your changes.

@jone thanks!
About the issue with DataGridField required + autoinsert, I will open an issue there, maybe I will try to fix it in future.

auto-insert is disabled in ftw.poodle = 1.5.0
