I have removed the Modified-Since handling as it did not have an effect due to the missing Cache-Control header, and instead added Cache-Control with a max-age set. This enables "forever" caching of icons, which should be fine since they are static assets. Signed-off-by: Florian Hotze <florianh_dev@icloud.com>

This enables "forever" caching of icons, which should be fine since they are static assets - they now have the same caching policy as files in $OPENHAB_CONF/the html folder.
Should be a nice change especially on mobile, where I can often see that icons need some time to load with slow cellular network.
