Fixing bug when a config only points to other config files and Switch to using simple glob instead of regexp

[Troejelsgaard]

(1) Fixing a bug that happens when a config only points to other config files, and (2) Switch to using simple glob instead of regexp (ignore the weird branch name that has nothing to do with was actually done)

First, the pull request fixes a bug where the queue was not returned correctly when a config files only points to other config files.

Secondly, the use of glob2rx() had some strange behaviours when trying to point to files with different extensions for example r vs R. For example when using "program.r|R" all R files in the folder was found and when using "program.[rR]" the "[" was not translated correctly.
Therefore, instead of using glob2rx() the code now only uses Sys.glob() The program read_regexp() has as consequence been renamed to read_glob() (and so has the function within this program)

@Troejelsgaard and @akselthomsen thanks for the PR!

Checked: Added support for logging of Python scripts with run().
Observations: Python Packages in the session info returns NULL although in the example script I have imported numpy and matplotlib - is this expected?

General: when a wildcard is used to run scripts in a folder, run (tries) to execute all the files in that folder regardless of file format. Lets restrict it to suported files (R, Rmd, Py, qmd)
