pywb 0.10.5

Another wombat overhaul for most accurate rewriting replay yet! Improvements to to <iframe> handling, postMessage and document.write

HTTPS proxy mode should work again where there were issues in earlier 0.10.x with wayback (using wsgiref by default as waitress did not support proxy at all).

New 'host scope' cookie rewriter, which rewrites domain cookies to current rewritten url host to avoid cookie leakage.
