Prevent creation of http images with invalid URIs

Active images should always be ready to be downloaded, regardless
they're locally or remotely stored. This patch prevents images with
invalid location URIs from being created and entering the 'active'
state with no data. This is only for the HTTP store.

Replace unicode() for six.text_type

To support Python3, unicode() calls has been replaced by
six.text_type.
Added utils.exception_to_str(): is the proper way to convert
an exception to string, since it manages logic related to
encoding.

Ensures that task.message is of type unicode

It is likely that a task script might store the message in a format
which is not 'Text', like a json message. To ensure that we save the
task message in the appropriate format, we should typecast it.

Use safe way through "with" statement to work with files

It's unsafe to just open and write to file. Cause if something went wrong
during writing to file we won't close fd.

Use safe way through "with" statement to work with files

It's good practice to use with statement to work with files. This way files get
closed automatically at the end of the block. Fixed some cases, including some
where file wasn't closed after usage

Remove all mostly untranslated PO files

We now only import PO files that are at least 75 % translated,
so we can delete now all other PO files. The patch only
removes the mostly untranslated files. Once a file becomes mostly
translated, the bot will import it again.

This removes all languages besides en_US.
