fixes #156

Seems like this change broke the functionality: cb1f39b#diff-0e426a43248661127a0c0ee115aef7a1093b635f8993b3f7ebb1dd9f05b8f249L295-R329

Reverting from:

if value, err := parseString(section, "Endpoint"); err == nil {

To

if sectionKey, err := section.GetKey("Endpoint"); err == nil {
	value := sectionKey.String()

Fixed the issue.

I'm not well versed in the code nor Golang for that to be an issue to revert to the old code, but it seems to work fine. And all the following lines still use the same method "if sectionKey, err := section." and so on.
