- revamped fmt methods for VData, VType, and some others => value == parse(value.fmtgi(..))
...
- updated debug() method to output static_type :: dynamic_type :: value
- updated to_string() to output "val" if called on a string (it just uses the fmt methods)
- updated format() to only take strings as arguments

added var_name var_type = statement syntax, which forces the statements return type to fit in var_type. This is useful if your initial value doesn't cover all types (like [ ...], which is a list with an inner type that cannot exist because there are 0 valid types, making the list completely useless. but arr [int/string ...] = [] expands that inner type to int/string, making the list usable)

added iterators: any function that takes no arguments can be used in a for loop. Each iteration, it will be called once. If its value matches, the for loop will execute its block with that value. If the value doesn't match, the for loop will stop. This also required adding function types: fn((input11 input12 output1) (input21 input22 output2)). The type maps inputs to outputs, because the add function isn't add(int/float int/float) -> int/float, but rather add((int int int) (int float float) (float int float) (float float float)) (notice that add(int int) can't return float and any other add can't return ints).

fixed a bug where the character directly following a float literal would be ignored (because parsing the float accidentally used that character). this is what caused [12.5] to break.

implemented working float literals and removed the 5,2 workaround: 5.2 is now a float! (see 10.5.debug()).
...
this was an issue for so long because it requires an exception to the usual dot syntax, and exceptions can be dangerous. So if there is an issue, you can resort to { 10.5 }.something() or { 10 }.5 (although this doesn't make sense) to convince the parser to do what you want.

- Added assume_no_enum() because the Err enum is used at least as often as [] for reporting fails.
...
- changed substring(a b) behavior from "b is the max length of the resulting string" to "b is the exclusive end index, unless it is negative, in which case its abs() value is the maximum length".
- fixed a bug in libs/path
- added the http_requests library, which can be used to make very basic GET requests
- fixed a bug in the gui library that would mess up button handling
- you can now escape comments using a backslash `\`: \// will turn into the literal //, \/* will turn into the literal /*. Useful for URLs (because comments work in string literals). Putting a backslash before a linebreak will also ignore that linebreak (useful in long string literals)
