Feature request: Add plain URLs to targets

[tadashi-aikawa]

Hi. Thank you for an amazing plugin😄

I thought it seems to be handy that not only jump to internal/external links, but also plain URLs.
So I tried to implement it as follows.

    getSourceLinkHints = (cmEditor: Editor): SourceLinkHint[] => {
        // expecting either [[Link]] or [[Link|Title]]
        const regExInternal = /\[\[(.+?)(\|.+?)?\]\]/g;
        // expecting [Title](link)
        const regExExternal = /\[.+?\]\((.+?)\)/g;
+       // expecting http://hogehoge or https://hogehoge
+       const regExUrl = /(?<= |\n|^)(https?:\/\/[^ \n]+)/g;

	const strs = cmEditor.getValue();

	let linksWithIndex: { index: number, type: 'internal' | 'external', linkText: string }[] = [];
	let regExResult;

	while(regExResult = regExInternal.exec(strs)) {
		const linkText = regExResult[1];
		linksWithIndex.push({ index: regExResult.index, type: 'internal', linkText });
	}
		
	while(regExResult = regExExternal.exec(strs)) {
		const linkText = regExResult[1];
		linksWithIndex.push({ index: regExResult.index, type: 'external', linkText })
	}
        
+       while(regExResult = regExUrl.exec(strs)) {
+       	const linkText = regExResult[1];
+       	linksWithIndex.push({ index: regExResult.index, type: 'external', linkText })
+       }

What do you think?
