Standardise beginning letter

[bobbingwide]

The SB list ( https://github.com/bobbingwide/bigram/blob/master/admin/SB.txt ) was originally created using first letter capitalisation. This allowed for proper names.

In the current website(s) implementation

• some of the S-words and B-words are capitalised,
• others are all lower case
• and some appear to vary.

It depends on where they're used and how they're created.
We need to standardise the capitalisation of the first letters based on how they're used.

Requirements

Here we'll use examples with S-word B-word as the two words.

Field	Value
Title	S-word B-word
slug	S-word-B-word
Category	S-word B-word
s-word taxonomy term	s-word
b-word taxonomy term	b-word
submitted image filename	S-word B-word.jpg

Where the logic should apply

• Sampled bigrams should be first letter capitalised automatically.
• Submitted bigrams should

Proposed solution

Implement filter hook for title_save_pre to ensure first letter capitalisation of titles which contain just an S-word and a B-word in the correct order.
