Lots of quality of life improvements (and bug fixes):
* Class(), ClassIf(), ClassIfElse() methods
* <wave:style> that can use a file vdom:/// url
* UseStateWithFn() to allow for functional setters
* If, IfElse, and ForEach for vdom construction
* batched updates for large updates -- streaming -- to get around packet size issues
* more flexible file sending code, for []byte, io.Reader, fs.File, and a fileName (with optional MimeType)
* fix the vdom:// protocol handler to work with fetch
* updated wshcmd-html for new best practices
* new vdomevents to support click, change, keydown, etc. easier type
signature
* can now pass a prop type instead of always converting to
map[string]any
* implement DefineComponent to allow easier vdom creation using a
component function directly
* separate vdomclient Make from Connect
* lots of bug fixes to get everything working again
* PStyle and special "style" attribute handling
json.Unmarshal parses all numbers to float64, which breaks any integer
settings values. This PR changes MetaSettingsType.UnmarshalJSON to use
json.Decoder, which is capable of parsing into a meta-type json.Number,
which can be interpreted as a float or an integer. It also properly
handles pointer types.
This migrates all remaining eventbus events sent over the websocket to
use the wps interface. WPS is more flexible for registering events and
callbacks and provides support for more reliable unsubscribes and
resubscribes.
Fixes an infinite loop in the layoutModel atom synchronization that
would cause the atom to update indefinitely when the root node is
deleted.
Also adds a dedicated `disabled` flag for the IconButton decl so we can
disable the onClick handler when the button is disabled.
Also updates the Magnify toggle button to use this new flag, so that
when there's only one leaf in a layout, the magnify button is disabed.
