Subtitles: Auto capitalisation/lower-caseification

[hellopaul4]

PPro often gets sentences/full stops/periods wrong - i.e. it'll transcribe something as the end of a sentence, adding a full stop and a capital letter (or vice-versa - neglecting to add a full stop/capital letter when the speaker has reached the end of a sentence). It's a bit tedious to edit both the full stop AND the capital letter on the next caption, and it'd be great if PPro could be set to recognise when I've changed the end of one caption to have a full stop, then auto-capitalise the starting letter of the next caption (and vice versa).
