plugin-loader rerun on reload

[aaronjudd]

As a developer, I wish that when the application reload or startup processes exit with Unable to resolve some modules:, the plugin-loader would rerun.

You can replicate this behaviour by switching branches where a new plugin has been added, while you have a running application. ie, switch from development to ek-email-templates (as of 0.17.0).

Example error:

=> Server modified -- restarting...
Unable to resolve some modules:

  "/imports/plugins/included/email-templates/server" in
/Users/aaronjudd/ongoworks/reaction/server/plugins.js (os.osx.x86_64)
  "/imports/plugins/included/email-templates/register.js" in
/Users/aaronjudd/ongoworks/reaction/server/plugins.js (os.osx.x86_64)
