[Zim-wiki] Clipboard still broken in Windows in rc2

Nope! Clipboard is NOT fixed. I was able to repeat the problem just now. Most of the time, copy succeeds. Sometimes, no TEXT value is copied to the clipboard. I am certain this isn't the fault of my Windows build process. If I can come up with steps to reproduce, I will add it here later today.

Backup your stuff before trying this. * Fixed breakage I caused in 0.67-rc2 release, where starting child processes (Edit Source, etc.) and decoding SVG files failed. * I think the clipboard may be working now. Let me know if Ctrl-C ever does nothing for you. * Re-instated Portable installer
