Make tag casing configurable

[lvanvugt]

Current situation

The casing of the tags being created based on input from ATDD.TestScriptor page is Sentence casing, meaning:

• Feature
• Scenario
• Given
• When
• Then

Desired situation

The user can determine themselves what the casing should be. A lot of existing tests currently use full UPPER CASING:

• FEATURE
• SCENARIO
• GIVEN
• WHEN
• THEN

It might even be that some only use full lower casing:

• feature
• scenario
• given
• when
• then

Maybe this can be implemented with a kind of template definition or regular expression.
