Significant string changes:
* sitepolicies, core_admin - 'Site policies' changed to 'Site security
settings'
* processexpirationstask, enrol_paypal - more explanatory name
* sitepolicy_help and sitepolicyguest_help, core_admin - setting will
only have an effect if the site policy handler is set to default
* sitepolicyhandler_desc,core_admin - improved wording
* pathtodot_help, core_admin - Windows and Mac paths
* debugstringids_desc, core_admin - improved explanation
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.
