Remote script configuration file "default.rjs" whose lines have the following format:
[script name]:[javascript code to return url arrays]

#### Activated scripts

Activate either local (bookmarklets) or remote js to execute the code on the similar sites with option "Activate user script".

Since activated scripts use internal mechanism of "i:0m" urls, the script itself cannot have 'H', '?' or '/' as its very first character.

#### Allow remote js on CSP (Content Security Policy) sites

All remote js (default.rjs) are allowed to execute on CSP sites. Local js files without remote resource access work fine when under the folder "bookmarklet", others needs to be refered in default.rjs as http urls such as "https://local/..." (html5 or offline cache) .
