Interactive map megaprint import/export still speaks about blueprints.

[kajahama]

Issue

The "IMPORT/EXPORT A BLUEPRINT" button on the SCIM left side and the following dialogs should refer to Megaprints now, and not Blueprints.
So all mentions of "blueprint" should be replaced with "megaprint".

Replication

Load a save in SCIM.
Start importing or exporting a Megaprint.

Actual Result

The button tooltip and dialogs still refer to Blueprints.

Expected Result

The button tooltip and dialogs should speak about "megaprints".
