Set python linter rule upon installation to preserve sentinels

[boltex]

For example, with the python language:

"python.formatting.autopep8Args": [ "ignore = E265" ],

Is needed with autopep for preserving comment '#' and '@' symbols without white space in between.

In the example above, the string "ignore = E265" should be added to the array of strings for the python.formatting.autopep8Args vscode setting.

Some similar settings could/should be added automatically for other languages.

Maybe ask user to confirm - recheck on extension activation.
