Fix issue with multiple matchers being overridden with the latest one

[PJnes]

I spotted this issue when attempting to add multiple matchers. It's difficult to spot why because I was only able to debug the compiled main.js file, but rule isn't always available when the onblur() triggers.

What I can't fully understand is why the index is available, but setting/getting the values directly from this.plugin.settings.rules with the index does seem to solve the issue.

Can you check if version 1.0.12 fixes the issue you observed?

I believe 6c71ad2 may have fixed this bug. If so, the problem was that the "Add New Link" button pushed a reference to DEFAULT_NEW_RULE to this.plugin.settings.rules instead of making a copy, such that changing any newly added rule would change all of them (they all referenced the same object).

@matthewhchan The new version seems to have solved the issue I was seeing. Thanks!

I'll close this.
