Merge all translations into monolithic files.

- This is a good thing

[#74408246]
Security Groups translation changes.

Probably should have waited until after we shipped this feature to
translate it. This was rather painful.

[#74818356]
Ensure manifest package translations are correct

[#74818356]
Fix translations for 'cf curl' command

[#74818356]
Make zh_CN json valid again

Noticed some json validation errors when we ran our tests against this.
The most common failures were

* {{.Templates}} were removed from english ID
* missing " or } characters
* ID did not match the canonical ID in other files
* {{.Templates}} not provided for translated string

We had to insert {{.Role}} in one of these -- we used google translate
to guess where it should go, but hopefully @wayneeseguin can help us
out.

Closes #205
Update translations
Move towards a global T function

- Also, deletes old unused translation files.
- Decouples translations from the source structure.  Sweet, sweet
  freedom!

[#74408418]
Removing old translations
New translations
Make T() a function directly on the i18n package.

- Remove all i18n_init files
- We now import the i18n package whenever you need T()
