form to upload a plugin jar in plugin tab
rails now delegates uploaded file to plugin manager
manager uploads the jar plugin to external directory
added test for view plugins
manager now returns a response; display a flash success message on the UI
Upload plugin form with localized labels, modified vendor output in gitignore
Removed duplicate form
Renamed plugin-file to plugin id for form
Validating jar file for plugin upload
Fixed the failing unit test. Notice that I've introduced a protected
method for better test coverage; a better way is to have a wrapper class
around the fileUtil so we can test the shit out of every
exception we'd like, but that'd a good follow-up refactoring commit.
Form formatting and updated localization labels. Flash error message styling
delegated writing and validating tasks to Writer and Validator from the Manager, respectively; first step to create a wrapper class around FileUtils - it captures .copyFile method only, for now.
revert the .gitignore change
show an error message when no file is selected for upload
Merge pull request #768 from pwen/plugin
