IniConfiguration.getSection() behaves inconsistently regarding dot escaping

According to documentation, dots in Keys should be escaped by doubling them. IniConfiguration.getSection() does not always recognise this correctly: When the section already exists, it works as expected. When the section does not exist, escaping is ignored, so

getSection("section.with.dots") will create a section called section.with.dots (consequently, getSection("section..with..dots") creates a sectoin called section..with..dots).

Additionally, the section return by the former call does behave strangely; it will only accept one call to addProperty().
