Support Linux 1.5 API #76
Description
Currently the library supports v1.0 of the Linux .desktop API. which is pretty universal. However, the API has been updated to v1.5 now, and supports many new attributes.
This library should allow you to pick either the newer 1.5 version or the more broadly adopted 1.0 version. Then adjust the verification to handle the differences around what is and isn't accepted for that version.
