v0.20.2

• the default component, used when no select '...' as component is present, is now table. It used to be the debug component instead. table makes it extremely easy to display the results of any SQL query in a readable manner. Just write any query in a .sql file open it in your browser, and you will see the results displayed in a table, without having to use any SQLPage-specific column names or attributes.
• Better error messages when a custom component contains a syntax error. Fix contributed upstream
• Lift a limitation on sqlpage function nesting. In previous versions, some sqlpage functions could not be used inside other sqlpage functions. For instance, sqlpage.url_encode(sqlpage.exec('my_program')) used to throw an error saying Nested exec() function not allowed. This limitation is now lifted, and you can nest any sqlpage function inside any other sqlpage function.
• Allow string concatenation inside sqlpage function parameters. For instance, sqlpage.exec('echo', 'Hello ' || $name) is now supported, whereas it used to throw an error saying exec('echo', 'Hello ' || $name) is not a valid call. Only variables (such as $my_variable) and sqlpage function calls (such as sqlpage.header('my_header')) are supported as arguments to sqlpage functions..
• Bump the minimal supported rust version to 1.77 (this is what allows us to easily handle nested sqlpage functions). Now all releases for all operating systems are compiled with the latest rust version.
