New line in strings in configurations/json

Rationale

In standard json, string should not contain newlines. They should contain "\n" instead, the standard symbols to represents a newline. Which clearly create a readability problem. In particular when an add-on configuration contains code (python, latex, whatever).

Thus, I wanted to have the right to have newlines in strings in json. And when I use the configuration editor, I want to see new lines insteads of \n.

Usage

This add-on allow you to write new line in your string. The add-on will replace them by "\n" before json load the configuration. This works both for configuration in the file meta.json, and for the the add-on manager's configuration editor.

Warning

Note that it will not put newlines in the configuration written in meta.conf. Indeed, this would create at least two problems:

• We can't control the order in which add-ons are loaded. Thus all add-ons loaded before this current add-on would fail when trying to read their configuration.
• If you decide to uninstall this add-on, no configuration with new lines could be read anymore. (In particular, this would happen if you synchronize your configuration using another add-on).

Internal

This add-on has an effect on ALL json strings read by the program. New lines in strings will always be removed and replaced by \n. Thus this add-on may affect more than configurations. However, this add-on call the standard json.loads() function, thus even another add-on affecting json.loads() should still be compatible with the current addon. Futhermore, this add-on has no effect on valid json. Thus the potential change would only be that some invalid json would be accepted, it seems harmless.

Furthermore, this add-on change ConfigEditor.updateText in module aqt.addons. It does not call the previous function, thus the current add-on will be incompatible with another add-on changing this method.
