KSP-CFG mode

A major-mode for editing Kerbal Space Program part (and other things) config files in Emacs.

Status

• Syntactic lex with good (well, enthusiastic and correct if not tasteful) highlighting
• Intelligent automatic indentation
• Context-sensitive advice in the minibuffer

Changes in 0.6

• Ack 2019
• Bump version
• Add emacs 24 req for lexical-binding (still optional)
• Appease checkdoc for symbols in docstrings
• Update cfg node keywords for 1.6.1
• Fix word/symbol syntax table entries for better word motion
• Prefer forward-line over (end-of-line) (forward-char) for better evil-mode compatibility
• Switch to cl-symbol-macrolet for end-of-indent-region checks for safer handling of over indented region at end-of-buffer.
• Reformat with indent-tabs-mode: nil because I can.
• Adjust (looking-back) use for modern Emacs 25.1+ 2-3 argument looking-back; should remain compatible with either.

To-Do features

• Set up travis-ci testing across various Emacs releases.
• Support more ModuleManager syntaxes; variables, regexps, and node-indexing aren't implemented.
• Refactor context help; a more flexible means of inserting new help tips on a per-module and per-keyword basis would help.
• Better context help for common node-keys and modules.
