Fix a rare cause of sync conflicts

Sometime in the past SQL datetimes saved to the server could be
interpreted as multipart dates, causing the date portion to be stripped
from the visible field. I fixed this previously on the server, but a
full sync could result in conflicts for any such values that synced
down. Instead, overwrite the local version (keeping Date Modified the
same) if there are no other changes.
Show redirect URL in the sync stream listener (for file downloads)

Also consolidate the display-URL-password-hiding logic in http.js
Fix error recovering from DB corruption maker if main DB doesn't exist

[RDF] QNAME fixes
* Allow periods in QNAMEs
* Don't break when there are illegal characters in the predicate. Use the strategy proposed at http://www.w3.org/TR/2014/REC-rdf-syntax-grammar-20140225/#section-Serialising (generate namespace that consumes all illegal characters)
* More robust namespace name generation

Closes #128
Log debug output to the Browser Console on Windows

At least for me (in a VM), the text console has always been unusable on
Windows. Logging to the Browser Console is slower than dump() on OS X
and Linux, but on Windows it's much faster.
Don't use browser console for logging in Zotero Standalone

This is probably what caused zotero/provo#5
