Steps to Reproduce (for bugs)

1. Ask me for a sample CSV that I've been working with.
2. Upload that CSV

3. Set the options for the import as follows:

It's confusing that it's called "Test mode" then. It should be called something like "Dry run" - let's discuss @raftaar1191 before you continue working on this one.

[DevinWalker]

@raftaar1191 after discussing with @mathetos here's how to proceed on this issue:

Testing Mode and New "Dry Run" Feature

Step 1

Shift the functionality you developed into a new "Dry Run" feature which allows you to "test" how an import will work to view duplicates and what items will be created before actually _importing_ any data.

Add new "Dry Run" Checkbox

Notice: I also changed the button text and touched up the styles. Please add this as well to the UI.

Change description of "Test Mode" option

Description should be:

Choose whether you would like the imported donations to be created in test mode or not.

Note: This option should be _disabled_ by default.

Step 2

Add a new "Dry Run" summary page.

When a "Dry Run" is performed the end result should be a summary page like so:

1. No data is created
2. Report is accurate reflection of live import
3. Admin can easily run actual import or tweak CSV and try dry run again

[raftaar1191]

For now, I am entering the donations in the DB and once it gets completed I will again delete all the donation entry

Will create another issue that will be refracting the Importer donation Dry run in which no entry will be added to DB

I'm bumping this to 2.0 milestone.
