Too cumbersome to add files to review

[ter@…]

It seems to only way to add files for review is to add each file, each section of those files. This renders the plugin useless for any real use. Code reviews are not done on one or two files, with a few lines in each of those files. They are done sometimes on hundreds of files, for the entire file. If a developer has done a major set of refactorings of a base compnenet for example.

There needs to be a way of merely specify a commit number to add all of those files. Individual files should still be able to be added, but when browsing, there should be a check box to include a file or a directory, allowing for more than one file to be added at a time.
