Labels for files in datasource

[likid]

Current behaviour

Files in datasource are labelled with their name.

Expected behaviour

Option to rename the label of the file opened. Today I read a lot of files from different folders but with the same name, so I have a lot of lines with 'console.log' label. I would like to be able to rename those labels to identify which server I am reading the log file.

Steps to reproduce the problem

Open files with same name from different folders without using folders in tailviewer datasource.

@likid Thanks for the suggestion. It hasn't occured to me to allow renaming single data sources (so far, only folder and merged can), but it shouldn't be too difficult.

I'm prioritizing this for a v1.1 release.
