* Add support for updating assets to the importer.
If an asset with a matching asset tag is found, and the --update flag is
passed to the importer, we edit the matching asset with any
asset-specific values, and persist to the database. Any missing/blank
values are skipped.
TODO: Add to web interface, add support in consumables/accessories
* Allow deleting of files on the import page.
* Extend web interface to allow updating of imported items.
This adds a modal dialog to the import process. Currently the dialog
allows the choice of update vs ignore, and choosing the item type to
import (Accessory, Asset, Consumable).
Also use Helper::ParseFloat() for purchase_cost processing. It exists,
and fixes issues on my end at least.
* Implement editing of consumables and accessories.
* Rename getProcessImportFile to postProcessImportFile to reflect how it's now used
* Fix copy-pasta error.
* Quote item names when displaying in error table.
* Remove the danger class as well as the warning class when uploading a file. Fixes a display error if a file is successful after a file fails upload.
