As of April 20, 2015, the old API used by repository_youtube is no longer
accessible. This change switches over to using the standard Google Data
API v3.
Unfortunately this means that to search YouTube, a developer api key is now
*required*.
Special thanks to UNSW for sponsoring this work.
From now on, all English strings use the new syntax. They are not
eval()'ed any more and the only valid placeholders are {$a} and
{$a->foobar}. No extra quotes escaping, dollar sign escaping and putting
double percent signs.
The modified files were exported from AMOS database repository in the
new syntax and were re-ordered by stringid. Standard GNU/GPL and PHPdoc
blocks are added. Where there was no copyright note so far, I added the
default one with Martin Dougiamas as the copyright holder.
Live long and prosper.
