First: Thanks for reviewing Jared!
Second: Re-checked all occurrences of `sprintf('%s %s` to make sure other translations are correct. Just found this one here to be not correct, so others are fine.

"This should be ´_S()´ because it is posting a permanent note to the task thread. Therefore should use the system language rather than the current user's language."

This commit updates a bunch of files and changes a lot of phrases. Basically it extracts "Internal error occurred" from existing phrases.
I've re-ordered the phrases so "Internal error occurred" is always at the end after the actual informative error message.

Example comparison before and after this commit:
Before: 1 Phrase: "Internal error: Unable to print to PDF"
After: 2 Phrases: "Unable to print to PDF." + "Internal error occurred"

Update three phrases with from "Internal error" to "Internal error occurred" since it's the most common phrase

Update two phrases with from "Internal error - Try again!" to "Internal error occurred - Try again!" since it's the most common phrase

This is required for system requests such as email piping. Since a user is
not logged in for the request, the system locale will not be set and text
might get corrupted based on the PHP configuration.

Updated several files to split up phrases like "Your lock has expired. Please try again!" into "Your lock has expiredx" and "Please try again!"

With the advent of the MANIFEST file, files which are rewritten when
deployed, such as those which have the GIT hash in the query string to force
browser reloading, were no longer deployed unless the content of those files
changed.

This patch adds a flag to the MANIFEST file to indicate that the file was
rewritten when it was deployed. This allows the file to be deployed and
rewritten again when the deployment is run, but also adds an indication
to the console output to distinguish deploying changes as opposed to
deploying rewrites.

Change to make one translation less since `%s is currently assigned to <b>%s</b>` is already used in ajax.tasks.php and ajax.tickets.php
