wix: restore COPYING.rtf This got truncated to 0 bytes in 0ab651b5f77c when the Phabricator extension crashed because it's a binary file. That caused the license page in the WIX installer to be empty. I don't remember if I needed to resubmit after the bug was fixed, so let's try this again with the current stable. If this fails, I'll retry with 5.1 to see if this is a regression in the API changeover last cycle. Differential Revision: https://phab.mercurial-scm.org/D8052

resourceutil: correct the root path for file based lookup under py2exe This silly copy/paste error caused "Mercurial" to be truncated from "C:\Program Files". The fact that "helptext" and "defaultrc" are now in a subpackage of "mercurial" added it back on, and everything seemed to work. But that broke if not installed to the default directory, and also caused TortoiseHg to look at Mercurial's config files instead of its own.

wix: use original version string for MSI filename Version string normalization is mostly to placate MSI requirements. I think it makes sense to use the original version string in filenames. Since we can have distinct versions normalizing to the same MSI version string, this will allow us to distinguish between different actual version strings based on the filename.
