Custom output/working directory for different file types

[mifi]

Currently LosslessCut allows saving output, temp files and project file all together, either:

• in the same folder as the input file
• or in a custom working directory (selectable by the user)

Some people have asked for more granularity:

• [ ] Allow storing project files in a separate folder #1536
• [ ] Performance: Allow storing temporary files (e.g. temporary pre-merge segments) in a separate folder (because sometimes writing them to the working directory is slow if it's not an SSD) #2112 - somewhat related: #963

I would also like to ask for another option than the mentioned two: relative to the input file, but in a subfolder.

Ideally I would like the project file (the .llc) to be stored next to the input file, which then can store were the temporary files were put to (e.g. a llc-temp subfolder in the same directory as the input file) and where the outputs went to (like llc-output). This way I could quickly reopen a project and easily tell what files were input and which were generated and can be thrown out in a month, while not accidentally deleting the output files.

Maybe I get the time to look at implementing this myself.
