jifmux: add "streamable" property
Submitted by min..@..arp.fm

By default jifmux uses the GST_TAG_MERGE_KEEP mode on incoming tag events, meaning that only the first attempt to set a tag counts.
This patch adds the streamable parameter, which if set to "true" will use GST_TAG_MERGE_REPLACE instead on tags.
This allows tags to be set on multiple JPEGs.
Patch is modelled on the flvmux element, which has identical behaviour.
