we now touch the messages before the actual update happens. this should
lower the chance of more than one update check running at a time.

In the recent refactoring of the HTTPClient, a problem with certain
systems was reintroduced. On these systems a select() call always
waits for a timeout on the first call before working properly on the
second call.

This patch reintroduces the shorter timeouts with usleep rate limiting
again.

Since this bug is not reproducible on other systems it can't be unit
tested unfortunately.

Added PAGEUTILS_ID_HIDEPAGE Event

fix E_STRICT errors FS#2427

add index file similar to fileicons to show active smileys

Appending files now works at least for uncompressed tar files. Seeking
in compressed tars is not yet supported.

You can give a path and file contents in an array. However this didn't
work because the file_exist() check was done before checking for an
array

Corrected typo: ruke -> rule

Removed acronyms for "Perl" and "PERL" as Perl is not an acronym.

Internet Explorer 8 (and maybe others) seem to use different
capitalization in the ACCEPT_CHARSET header between "normal" requests
and AJAX requests. This causes a browser UID mismatch and thus an
unecessary reauthentication.

Made bin/striplangs.php executable
