Simplified steps required to setup development build for new contributors

[HarleyGilpin]

What has been done?

• Launcher will now auto install cache files if they are missing
• Xteas are now included by default in the repo.
• Owner privileges are given to all new accounts by default if environment is set to "development"
• Refactored project using the folowing Ktlint configuration:

root = true

[*]
charset = utf-8
insert_final_newline = true
trim_trailing_whitespace = true
max_line_length = 120
indent_style = tab
end_of_line = lf

[*.{kt,kts}]
indent_style = space
indent_size = 4
ij_wrap_on_typing = true
ij_any_wrap_long_lines = true
# noinspection EditorConfigKeyCorrectness
ktlint_custom-rule-set = enabled
# noinspection EditorConfigKeyCorrectness
ktlint_standard_function-expression-body = disabled
# noinspection EditorConfigKeyCorrectness
ktlint_standard_function-literal = disabled

[*.md]
max_line_length = 80

Has your code been documented?

• Yes.

Is there a check for .gitignore in the cache directory? We should explicitly ignore this file unless it’s ignored already. Aside from that, ready to merge
