add notext option, fix paste without text handling

Now text is taken if no `--notext (-q)` argument is passed.

If that flag used, paste will be created with empty text,
but file for send must be specified

If `notext` arg is not used, text will be taken in next order:
* from `--text (-t)` argument
* from stdin (forcibly)

Here's no ability create paste without any text.
