use modern browser support for natively parsing query parameters

Details are within a thread on the Picobrewers facebook group between myself and Patrick on debugging why when clicking a link from Facebook wouldn't render.

Example of what doesn't work (shows a spinner): https://pbrecipes.beer/recipe.html?id=a37ad562c49046709edf4be9cc6a4ac0&second=parameter-incorrectly-parses-due-to-parsing-logic

According to https://caniuse.com/?search=URLSearchParams I believe most up to date browsers support the URLSearchParams API so we can rely on this. If people report issues we may need to make a shim to work around that.... but most should be using modern enough browsers these days.
