table with hashsums of deleted files

[LebedevRI]

perhaps there should be a table with hashsums of deleted files, so that people don't just reupload it easily after we delete

[LebedevRI]

but then there should be some way to bypass it, in case we upload a sample that got removed accidentally

[LebedevRI]

• the table should retain the message we already enter when deleting a sample, and the message should be displayed instead of successfull upload screen
