LiveScript 1.4.0 发布，包括 Source Maps

LiveScript 1.4.0 发布，此版本包括 source maps；功能性 JSON 命令行处理；改进生成器支持；大量 bug 修复。

更新内容如下：

• Changed npm name to livescript as npm no longer allows publishing updates to packages with upper-case letters

• Added source map support using the -m,--map flag

• Added command line JSON processing with JSON and the -e,--eval flag. Inbound JSON is bound to this

• Fixed a regression from previous versions that did not allow for flag style positionals after a first positional (eg. lsc app.ls --flag caused an error)

• Generators are no longer auto-hushed, moving behavior in line with what was expected

• Allow backcall generators, eg. *<-

• Added back -k shorthand for the --const flag

• Made it possible to use the by keyword in slices, eg. list[1 til 5 by 2]

• Object comprehension bug fixes

• Fixed various backcall issues

• Fixed composition operator spacing issues

• Yield bug fixes - including allowing it to be used with no operand

• Replaced deprecated usage of customFds in child_process.spawn

• Added CLI tests

• Many other bug fixes
