Alternative pattern for matching local imports

[Xarvalus]

Closes #14

Hi, I've managed some time to try to solve your issue, hope will be useful :)

Current solution is far from being perfect, nonetheless as alternative, matches local imports in one .replace() cycle and passes assumed tests.

Drawbacks:

• current master code badly matches in dependency import (previously reported in issue),

  -    import NodeButtonComponent from 'node-component/lib/Button'
  +    import NodeButtonComponent from 'node-component/lib/AnotherButton'

• the naming of import is not changing, IMO it's 'ok' as fair as we are not replacing inherited imports usage (eg. <SimpleButton> in code is not replacing currently)

  -    import SimpleAnotherButton from './SimpleAnotherButton'
  +    import SimpleButton from './SimpleAnotherButton'

There is possibility for making it more readable/customisable by running multiple .replace(), but it would suffer from performance penalty and unexpected overwriting.

Let me know about your thoughts on my contribution, thanks!

Fair point, after change regexp supports now both single and doublequotes in import.
