Duplicate ARM Assets

Each Electron release includes two identical ARM builds with slightly different filenames, like electron-v1.7.3-linux-arm.zip and electron-v1.7.3-linux-armv7l.zip. The asset with the v7l prefix was added to clarify to users which ARM version it supports, and to disambiguate it from future armv6l and arm64 assets that may be produced.

The file without the prefix is still being published to avoid breaking any setups that may be consuming it. Starting at 2.0, the un-prefixed file will no longer be published.

For details, see 6986 and 7189.

FIXME comments

The FIXME string is used in code comments to denote things that should be fixed for the 2.0 release. See https://github.com/electron/electron/search?q=fixme
