v0.4.0

Changes

• Create one plume.lua file per Lua version.
• Add error message (instead of crash) for wrong type in operation on token with implicit rendering.
• Add error message (instead of crash) for errors in external Lua files.
• Add error message (instead of crash) for unexpected errors inside plume code.
• Prevent implicit rendering from calling keys on numbers, or non-string methods on strings.
• Add an error if user try to render a nil code.
• Rename api.getl to api.lget to avoid confusion with api.setl. (l stands for "Lua" for one, "local" for the other).
• New token:is_empty ()
• New api.export ()

Fixes

• Fix implicit rendering not working with string methods.
• Fix token.__unm not working.
• Fix an error occurring when there are comments between \if and \else.
