Try to support options before first section

[szaghi]

It is often allowed, in many config format, to insert options before the first defined section, e.g.

foo = bar
bar = foo

[first-section]
baz = first

Presently, the two options foo and bar defined before the first-section are omitted. Consider to try to parse them.

Some parsers put these orphans options into a default section intended to have a global meaning... it can be the right way.
