Git.pm: config_boolean() -> config_bool()

This patch renames config_boolean() to config_bool() for consistency with
the commandline interface and because it is shorter but still obvious. ;-)
It also changes the return value from some obscure string to real Perl
boolean, allowing for clean user code.
