Add support for IchigoJam BASIC (#1246)

* Add support for IchigoJam BASIC

Hi. This PR adds support for [IchigoJam](https://ichigojam.net/), which is a board that using its own BASIC language, so I was not extending this from `basic`, but submit as a standalone language.

If there're anything necessary to change, please reply to me and I'll respond to you ASAP.

* Requested modifications have been made.

And after digging into the docs, IchigoJam actually use a very small set of ```basic``` and it adds a different set of markers to its own ```basic``` language, so I just keep this as a standalone language.

* fixed the regexp for comment, number, operator and punctuation

For IchigoJam, the space is not required to be appeared after the ```'``` or ```REM```.

Add support for binary and hex numbers

Specified for IchigoJam

Add ```[``` and  ```]``` for IchigoJam

* Add example code for IchigoJam.

* Add test-suite for IchigoJam

* Add prism-ichigojam.min.js
