Enable input for search function by 1D/2D barcode scanner of Zebra device TC72

[bdeboeck]

Currently, when using the search function (magnifying glass) in Intercross app, it is only possible to scan cross_unique_id barcodes using the camera scan using the TC72 device. Would it please be possible to also enable the use of the dedicated scanner for providing input in the search function? Scanning works then much faster and without issues. The zebra device is TC72 (or TC720L) with zebra's SE4750 OEM Array Imager Scan Engine.

#126 which is in PR #167 will make it so that long-pressing the search opens a text box that would be compatible with dedicated external scanners, but we could also add a setting that shows the text entry by default.
