Try to register all javascript files found in themes as handlebars
helpers.
Note that, unlike all other theme files currently, format directories
are ignored. I don't think there's a use case for format-specific
helpers, and this gives theme developers the flexibility to put them
either in top level files or organize them in subdirectories however
they see fit.
Note also that the theme format seems to be primarily documented in
<https://github.com/fresh-standard/fresh-themes>. This newly recognized
theme file type should be documented there should this branch be merged.
Rebind Handlebars helpers to drop the pesky options hash for standalone
helpers that don't need it. Move block helpers (which do need the
Handlebars options/context) to a separate file for special handling.
Fix output file name glitch, writing CSS files to destination folder,
and an issue where the process would evaporate before PDF/PNG generation
could complete.
Add support for detection of invalid line breaks in JSON string values.
Fixes#137. Could be improved to fetch the column number and drop the
messy grabbing of the line number from the exception message via regex,
but currently the "jsonlint" library (not to be confused with
"json-lint") only emits an error string. Since this is also the library
that drives http://jsonlint.com, we'll accept the messy regex in return
for more robust error checking when our default json-lint path fails.
All of the above only necessary because standard JSON.parse error
handling is broken in all environments. : )
Merge implicit and explicit generation paths, start emitting file
transform & copy signals, fix various bugs, introduce new bugs, support
better --debug outputs in the future.
Remove file-based open methods from resume classes; force clients to use
clean string-based or JSON overloads; fix processing glitch in
validate(); tweak outputs; adjust tests; update CHANGELOG; etc.
