Reformat getInfo function

with previous commit, Fixes #681
authplain: Escape ':' in any data field as '\:'

':' is the field delimiter in the authplain flat text
conf/users.auth.php file, but it's also used as an internal delimiter
for the 'mediawiki' password hash format. Currently using this hash
format corrupts the file

This change escapes ':' as '\:' in any field in the users.auth.php
file, and any '\' as '\\'.

Also adds test cases for escaping modes.

rephrased error message. #681
upgrade to jQuery 1.11.1 and jQuery-UI 1.11.0. #778

This now pulls all data from official jQuery sources. Either their CDN
or their github account. Google tends to serve outdated or even broken
files :-(

Unfortunately there's no simple way to get the latest stable jQuery-UI
so for now the version has to be adjusted manually in the script.
allow for easier HTTPClient debugging

Sometimes users report bugs or problems releated to HTTP connections
made by our HTTPCient (eg. in the extension manager or XMLRPC).
Debugging those problems previously required modifying some sources to
enable the debugging output of the HTTPClient.
This patch adds a way to enable the debugging via a request parameter.
Since HTTP requests are often done only *after* some button was clicked,
the parameter is also looked for in the referrer of a request.
Debugging output is enabled through the existence of the parameter
'httpdebug' and is directly printed to the screen. Debugging HTTP only
works when allowdebug is enabled.
