Translation for the web client (and other interfaces)

Evergreen master

As discussed in IRC around http://irc.evergreen-ils.org/evergreen/2015-08-06#i_194112, we need to make some changes to the Makefile under build/i18n/ to account for additional translation needs. Most specifically for this bug, I'd like to propose some initial changes for the Makefile to include the creation of a translation template for the new web based staff client from Open-ILS/src/templates/staff/..

Included here is an initial working branch that adds a new pot file called webstaff.pot that includes all the current translation strings from the staff directory for the web client.

See: user/bshum/i18n-for-webclient

Dan Scott suggested to me that we may want to also include other Makefile changes for other targets, like any new/missed dojo ones, or KPAC too.

More to follow, not putting a pullrequest on the changes yet while we look at things further.
