Actually is here!

New Features
- Python 3 port (sorry Python 2, you just aren't good enough anymore)
- Ability to read UTF-8 encoded source code and input and write UTF-8 encoded output
- Implicit input
- Better organization (but it still needs work)
- Better numeric and list parsing
- Under-the-hood performance enhancements
- More commands
- Changed some existing commands around in the command list
- `commands.txt` is now UTF-8 encoded, so it renders properly in GitHub and most text editors without additional changing of settings

Actually is not backwards-compatible with Seriously. This is a good thing.


Windows
The executable contained in this release will create a lightweight installation of Cygwin, and automatically download Seriously and install the prerequisite(s).

So much stuff has been added and changed; it's probably time for a new release. I guess.

More commands! A working online IDE! Still no docs. Oh well, 2 out of 3 isn't bad.

Function values now work, which means that every command currently in the commands.txt file works!

Complex values now work, and all complex-valued commands have been implemented.

Numeric literals now use ":" as a delimiter, rather than a prefix.
