Refactor snapshot support

The snapshot support needs to be split between output- and config-related functions to get the layering between shared.c and ui-*.c right. There is also some codestyle-issues which needs fixing to make the snapshot functions more similar to the rest of the cgit code. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
