core: Move default bridges to whitelist.default.txt

Browse source 
Default bridges are currently statically defined in index.php, which
is not the right place if we want to keep responsibilities separated.

This commit introduces a new file whitelist.default.txt that holds
the default bridges and which is loaded automatically, if whitelist.txt
doesn't exist.

Due to this it is also no longer necessary to have write permission
for the root directory.
