Fixed url hostory init bug.

If the browser read the history from file in the init function the history max
items where not set so we considered the max items to be 0. Now the url
history is initialized if the config is processed.
Fixed wrong config pathes in man page.
Removed dependency to m4 processor to build manpage.

The overkill of the m4 isn't required to simply replace VERSION and PROJECT in
the manual page.
Renamed the option to dump config to stdout.

Added the new config to the manual page.
Use the MFLAGS for every make call to a subdirectory.
