The displaying of advanced items has been refactored. The changes are:
* The Advanced button is replaced by the Show Less/More link
* The Show less/more link controls advanced elements only within the section
it is located at
* The Show less/more state of sections is preserved between form submissions
* When javascript is off, all advanced elements will be displayed by default,
no show/hide controls will exists on the page
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.
