* Config file support
* Some naming changes to command line options

POSIX doesn't grantee that a blocked Read() operation will be released
after closing the file. Moreover, the pty file left intact even after
closing the file and the process keeps running in this case.

* New `--title-format` option to specify window titles
* Terminal profile support is added
* ARM architecture support
* New `--auto-reconnect` option to reconnect to the server
* TLS/SSL option by `-t` option
* `--once` option to shutdown the server after the first client exits
* Better UTF-8 input support

When `send-encoding` is `utf-8`, hterm translate input from the
clipboard from UTF-16 to UTF-8, even when the input is indeed UTF-8.
This translation messes up all non ASCII input.

This change prevents the listener from closing itself before
establishing the websocket session with the client.

fix typo

A new option `--auto-reconnect` which takes seconds to reconnect is
added.

So that users can open IPv6 URLs on web browsers.

`os/user.Current()` is not available on Darwin when a binary is cross
compiled from another platform.

* Client PTYs are closed properly without EOF byte
* Added the "-r" option to generate random URL by @shoz
* Added BSD support

Mentioning hterm and wetty so that people don't get confused that GoTTY
has an original terminal implementation.
