2015c and 2015d data updates

[timrwood]

See #205

@timrwood - Why are the "untils" being truncated here?

[timrwood]

I also included 2015d which removed DST in Egypt. http://mm.icann.org/pipermail/tz-announce/2015-April/000031.html

I still see way more data updates in the unpacked files than are actually in the tzdb releases (as far as I can tell). Are you just running grunt data:2014c or something different or more than that?

FYI - that's all I did, and was on a clean Ubuntu box when I did #205, so it's not a line-endings issue. Currently we actually can't build the TZ files on Windows due to dependencies on zic and zdump.

Also - the contributing guide describes how to compile these files, but it doesn't describe how to build the moment-timezone-2010-2020.js and moment-timezone-all-years.js files to update the moment-timezone home page - which currently still references 2014j. We need to get this all straightened out. (please)

Merging as is, though I could still use additional instruction in this area. Thanks.

@mj1856, moment-timezone-2010-2020.js and moment-timezone-all-years.js are built with the grunt release command.

Is there an ETA of these updates being released?
