Bug Report: Tokenizer failed to handle the final line of listed projects when missing newline character

[Xiaoven]

Steps to reproduce

When prepare the file assigned to FILE_projects_list in config.ini, DO NOT end with an empty line:

path/to/project1.zip
path/to/project2.zip

Run python tokenizer.py zip, then check the log file and see:

[INFO] (MainThread) Starting zip project <1, path/to/project1.zip> (process 0)
...
[INFO] (MainThread) Starting zip project <2, path/to/project2.zi> (process 0)

The path of the last project is handled incorrectly which results in project not found.

---

This may caused by proj_paths.append(line[:-1]) in tokenizers/file-level/tokenizer.py .

Recommend to use line.strip() instead of line[:-1].
