Lobster language support

[inferrna]

Description

• I am adding a new language.
  • The extension of the new language is used in hundreds of repositories on GitHub.com.
    • Search results for each extension:
      • https://github.com/search?type=code&q=NOT+is%3Afork+path%3A*.lobster
  • I have included a real-world usage sample for all extensions added in this PR:
    • Sample source(s):
      • https://github.com/aardappel/lobster/tree/master/samples
    • Sample license(s): Apache v2
  • I have included a syntax highlighting grammar: https://github.com/inferrna/lobster_ling
  • I have added a color
    • Hex value: #f95428
    • Rationale: extracted from https://strlen.com/img/lobster/lobster.svg

We really don't need that many samples. 2-3 of the most representative of common usage is enough.

A cached copy of the grammars licence should have been created when you ran the script/add-grammar command. This file needs to be included in this PR.

I added a license file. Also I did re-upload https://github.com/inferrna/lobster_ling repo. Originally it was a fork of https://github.com/aardappel/lobster which seemed a little too much.

Please revert your last two changes. Submodule names are based on the upstream repo name. Your upstream repo is still lobster_ling so the submodule name should remain lobster_ling too. If you want to rename the submodule, rename your repo and re-add the grammar.

PR looks good now. The language isn't popular enough for inclusion yet so I'll leave this pending popularity and review. Popularity is re-assessed each time a new release is made (~ every 3-4 months). This issue will not be updated with each check and there's no need to keep merging master in but please keep an eye on the PR and address any conflicts if they crop up.
