This family of IDE with Erlang plugin is already quite popular.

Used a nonexisting option instead of a correct one

Issues formerly were avoided by quoting atoms. Unquoting them created
unbalanced tags (`{{{name}}`) which were mistakes. This patch inserts
spaces to unconfused bbmustache.

hex.pm is now using maintainers instead of contributors in metadata.
Templates should be updated to reflect it.

Some templates like OTP apps are usable within releases, so the text
does remain a bit vague, but hopefully less than before.

- The OTP app template now adds the supevisor
- The default apps_dir value does not contain the trailing '/' that the
  template index already added.

The first variable can be unkeyed and the provider will sub in the
variable name 'name'. Additionally, the built-in templates and
documentation have been updated so that 'appid' is now 'name' and the
alternative commands are shown.

This totally breaks compatibility with rebar2, and maybe it shouldn't
have.

When a node is configured with -sname the REMSH_NAME_PART argument should be defined with using command 'hostname' but error occurs due extra space
