Add an include to a member when it is part of a namespace or module.

This behavior can be triggered through the option
SHOW_GROUPED_MEMBER_INCLUDES.
Enable EXTERNAL_PAGES.

This option has the same effect as EXTERNAL_GROUPS, just for pages.
BUG: When EXTRACT_ALL is enabled, superfluous detail sections are enabled
Add a proper gitignore.
Make configgen.py portable.
Link less in the member table

When no detailed section is visible, don't make the name a link.
