[FIX] tools: mail transcoding css space consistent

The transcoding of a mail (transforming CSS into inline styles on the
element nodes of the mail) used the form:

 property:value;

So when a mail is saved, it would be eg. with `style="property:value;"`
and when it is being edited "property:value" is removed if available via
CSS stylesheet given the structure.

But the sanitize_style (introduced in bfe7aafa7) adds an espace before
the value (which is more pretty but was probably not choosen in
transcoding to decrease size of mail):

 property: value;

so the inline style would not be removed when editing possibly causing
conflict with the editor.

With this commit, the sanitize_style doesn't add a space. It could have
been changed in transcoding but the code is already rather slow and we
don't want to use a regex replace or two string replace instead of the
current one string replace.
