Issue #156: Added lib path segment to classpath

When starting syncany as daemon in Windows, plugins installed with sy
plugin install webdav are not recognized. The reason is, that in the
plugins are stored in %AppData%\Syncany\plugins\lib\* but sysd.bat sets
the classpath to %AppData%\Syncany\plugins\*. This commit resolves the
issue.
