ini enhanced error handling; test file

[utoddl]

This enhances error handling in ".ini" files, and creates "test/ini-test.ini". The "test" directory should contain example files demonstrating features and problematic issues with an eye toward regression testing as new features and bug fixes are implemented. In only has the ini-test.ini file at the moment, but this should expand over time.

This is a great idea @utoddl - thanks for going ahead and proposing a test case for INI files. I think manually checking the test files for weird highlighting is the best of what we can achieve with joe for now although I would really like some semi-automatic way in the future... comparing against screenshots or something.

I'm currently a bit busy but will merge when I have some free time since I also wanted to restructure repo a bit.

Glad that idea appeals to you.

I also put a mention of the license directly in the .jsf and the test file. I found reading about the licenses confusing when trying to figure out which applied to specific files, especially once those file are "in the wild". Some of them are shipped with ne, which also uses joe's syntax engine, so having the license in the file is a big help. Leaves in the wind, etc.
