Tweak `@GlobalScope` functions documentation overall

Generally:
- Made use of [param] more frequently;
- Link to other classes' documentation more often;
- Improve and add more examples;
- Ensure that multiple comments of an codeblock example are spaced out equally for better readability;
- Made the writing style closer to how the rest of the documentation is formatted;
- Ensure these are called "functions", not "methods".
- Fixed a few typos.
- Touched up a few cases of zero being written as "zero" or "0" where "0" or "0.0" would be more appropriate.
- Removed mentions of "(real)". In 3.x, this was associated with floats, because TYPE_FLOAT was called TYPE_REAL.

More specifically:
- Every type-safe version of a function (such as `ceili` has a consistent final note ("A type-safe version of [method ceil], returning a [int]").
- Added more details to `randomize`, `seed`.
- Corrected `floori()`'s description. It's not the same as `int()`. This was not correct behavior and has been fixed.
