Trim down the multi-module project into something of a more manageable size, refactor silliness.

[kutis96]

Rationale

The current multi-module setup is rather cute, however, moderately pointless.

Many modules could be merged into one, as they are likely to be used together anyway.

• spacedoc-common
  • likely to be used by all the things, according to the name
  • has a few utilities and somewhat common types, but not quite all of them
• spacedoc-cdi
  • slightly silly name
  • is probably the actually most commonly used component alongside config
• spacedoc-config
  • actually used by almost everything
  • extremely heavy, there definitely is some room to trim some excess code here
• spacedoc-ffc
  • Probably good, do keep split off
  • A rename would make sense, perhaps to spacedoc-external-renderers?
• spacedoc-markdown
  • Do keep split off
• spacedoc-executable
  • It is robably smart to keep split off for more modular builds in the future.
  • Somehow contains MarkdownModule and LanguageRendererModule. Those should be moved to spacedoc-markdown and spacedoc-ffc respectively.

Tasks

• Merge spacedoc-common, spacedoc-cdi, spacedoc-config into spacedoc-common
• Move MarkdownModule and LanguageRendererModule into spacedoc-markdown and spacedoc-ffc
• Rename spacedoc-ffc to something more sensible
• Rename all groupIds to in.spcct.spacedoc
• Rename all artifactIds, removing the spacedoc- prefix
