Support Unix absolute and relative paths in Jump-to-file module

[maiermic]

Jump to file under cursor does not work most of the time. I try to use it on an \input{path/to/file.tex} with the cursor between the curly braces. I use Chrome 71.0.3578.98 on Linux Mint. So I press Alt + G, but nothing happens even though path/to/file.tex should be opened.

Do you use relative paths such as ../path/to/file.tex? Because they are currently not supported.

[maiermic]

No, my paths start always at the project root directory and are not relative to the file they are referred from.

[hrjakobsen]

It does not work with unix paths such as /path/to/file,./path/to/file or ../path/to/file. This is something that I've wanted to implement for a while now. I will update the issue to reflect the problem.

Work has begun on this in 96b88d5. It will need some more testing, but I have made it possible to extract the file-tree structure from overleaf, so that we can traverse paths with ../ and ./.
