TexError Localisation 1

[zorkow]

PR

• Merges the old Error message into the new framework
• Moves the JSON files into the correct place
• Adds components constants for loading json
• Fixes all erros to work with the new framework.

There is some overlap/duplication between messages in [tex] and [tex]/base components.

NOTE: 02b3b4a (the actual merge) is in the wrong order due to a timing issue between my laptop and my desktop.

This looks good, modulo the issues we discussed face-to-face, and that you have fixed in later PRs. I have made a few small suggestions, and point out one place where there seems to be an issue with added code that shouldn't be there.

Thanks for rebasing and going through the PR in details.
Many of the issues you pointed out are probably down to merging of old versions of code that was later linted or incorrectly resolved merge conflicts. In particular, I have now recollection of making any major changes to UnicodeConfiguration!

Worked on the comments. PTAL.

This looks good.
