New batch of SVG icons

[IanMayo]

I have a requirement for a new batch of icons, to add to those in the counters/white folder.

They will all be simple white SVG vector files.

• water plume (something like this)
• flash: 6-pointed star
• periscope: like this
• wake (a series of V shapes, one inside another)
• general audio event: ear
• general visual event: eye
• general audio * visual event: combined ear and eye
• general event: exclamation mark

Done.
