constant FICHINTER_WITHOUT_DURATION to handle interventions without duration in lines

include expense reports in linked objects section and provide template for them in this section

NEW Update accoutancy with last dev

Adds the translations for all languages having the MAIN_MAIL_EMAIL_TLS
const defined. It's just a copy of this last one changing the "(SSL)" by
"(STARTTLS)".

Adds a STARTTLS authentification option. This is used by Microsoft
Hotmail and Exchange. This commit includes a new constant named
MAIN_MAIL_EMAIL_STARTTLS, a view and edit view for it and the edit
action needed to modify value in DB. It also updates the js function
initFields to make it behave like the standard TLS option and adds two
jQuery function respectively to set TSL off when STARTTLS is selected
and to set STARTTLS off when TLS is selected. Unselecting one of those
won"t select the other.

Adds the STARTTLS connection mode in function _server_authenticate. It's
use by Microsoft Hotmail and Exchange servers. I use the
MAIN_MAIL_EMAIL_STARTTLS const introduced in admins/mails.php retrieved
from the $conf object which is not used anywhere else in the file so it
may not be the right way to do it. Maybe this value should be passed in
constructor but it would then imply more changes around multiple files
calling smtps class.
