Enable more linters, address the issues and do a major naming refactor
to use golang lower camelCase identifiers for types, functions, methods
and variable names.
Also:
* Clean up inline generation so it doesn't rely on temporary variables.
* Remove unused functions generated by inline.pl.
Update underscore.js to v1.13.6.
BREAKING CHANGE: This changes the behaviour for the following underscore
functions, please see underscore.js documentation for details.
* .template
* .keys
* .after
* .range
* .reduce
* .reduceRight
* .reduceLeft
Fixes#110
