i#1620 WIX integration: add DrMem to user PATH

The WIX installer now unconditionally (i#1761 covers adding checkboxes)
adds Dr. Memory to the user's PATH.  This *should* be auto-removed on
uninstall but that is not working: i#1762 covers fixing that.

This CL updates the docs to reflect the new automatic PATH editing.

The WIX installer now has enough of the features of the NSIS installer that
WIX support is declared complete.

Fixes DynamoRIO#1620

Update DR to r2833 for DRi#1521 win8x86 fix.

That pulls in the new drfrontendlib link with drdecode which requires a fix:

DRi#1409/DRi#1503: we get link errors about dup symbols dr_get_stderr_file()
in drdecode and dynamorio libs unless we link drstrace_unit_tests w/ drinjectlib.
