Embed go timezone database in Windows build

[malcom]

Hugo87 with specified timeZone in config exit on Windows with msg:

Error: invalid timeZone for language "en": The system cannot find the path specified.

This is a known problem with golang time lib on Windows (golang/go#21881, golang/go#38453) with missing zoneinfo.zip file.

User workaround for this problem could be:

• extract zoneinfo.zip file from golang distribution and set the path for it in env %ZONEINFO%
• install golang distribution

But, it seems a much better solution would be to embed the binary content of this file when building the windows version. Package tzdata provides an embedded copy of the timezone database.

One learns something new every day. We have tests that run on Windows, but those servers all have Go installed.

I have pushed a fix for this, a fix I don't have any easy way to verify myself. I assume it will work, but it would be good if someone could chime in and tell me that it works.

I could test, but I'm not a Go programmer, so if you provide the v0.88-dev build, I'll check on Win7 and 10.

@malcom attached is the dev build (extended version) for Windows.

I tested and confirm that it works correctly :)
