* Allow tabs for the indentation added by the code actions feature (#673).
The previous implementation always assumed spaces for indentation.
But in stage2 code may contain tabs for indentation as well.
* Fix some edge cases, properly detect indentation(any amount of spaces) and move the indentation code inside `createDiscardText()`.
* adds reformatting to camelCase for function names
* removes useless +1 byte when allocating a string
* added some forgotten functionality
* fixes an issue caused by auto-fmt & changes action kind
* fixes several issues related to camelCase action
* fixes a bug if a fn name is all underscores
* sets camelCase action to quickfix
* sets camelCase action to sourceFixAll
* fixes a mischanged line
