Blank STP fields cause an error when we load the file

[ac2cz]

For example, when RF-Receiver Description was not completed then the STP Raw Queue could not be sent to the server. This is because it is read in with a tokenizer and it does not like blank fields.

The error needs to be fixed in Frame load(BufferedReader input)
Rather than tokenize the line we should split it.

If the frame queue is corrupted because the line was not fully written then I think we also get a crash

I have mitigated this by making sure that the setting always has a default value and can not be blank. But it should be fixed fully.
