+ * - transform module code before it's sent to Espruino with Modules.addCached (we only do this if we don't think it's been minified before)

+ * disconnected - disconnected from Espruino (no data)
+ * environmentVar - Board's process.env loaded (object to be saved into Espruino.Env.environmentData)
+ * boardJSONLoaded - Board's JSON was loaded into environmentVar
+ * getModule - Called with data={moduleName:"foo", moduleCode:undefined} - moduleCode should be filled in if the module can be found
+ * getURL - Called with data={url:"http://....", data:undefined) - data should be filled in if the URL is handled (See Espruino.Core.Utils.getURL to use this)
+ * terminalClear - terminal has been cleared
+ * terminalPrompt - we've received a '>' character (eg, `>` or `debug>`). The argument is the current line's contents.
+ * terminalNewLine - When we get a new line on the terminal, this gets called with the last line's contents
+ * debugMode - called with true or false when debug mode is entered or left
+ * editorHover - called with { node : htmlNode, showTooltip : function(htmlNode) } when something is hovered over
+ * notification - called with { mdg, type:"success","error"/"warning"/"info" }
