Parse multiline values

[jonmagic]

@joelvh tonight I had to revert #318 and #329 as #318 introduced a parsing regression (#336, #339, #341). We would be happy to review a follow up PR that re-introduces the feature and passes the regression tests I added in b023c9b and 294ab7b and maybe adds a few more tests.

@jonmagic looks like a test is missing for #339, which is not a commented line, but a variable with no value. I've created #344 to add the test until I've got a solution for these regressions. Will report back when I've got something!

@jonmagic #346 fixed regressions that were reported in v2.3.0

@jonmagic would be good to get #346 merged. I have a configuration that's hard to maintain on a single line with \n.

Thanks for getting this in @cadwallion :)

I'm using a fork of the project with this included. I will switch back to the original once a new release is pushed out.

Version 2.5.0 was just released, sorry for the wait!

Thanks @cadwallion !
