Create browser build for metaschema

[georgolden]

To-do

Only place, where we have metavm - lib/loader.js

• exclude lib/loader.js from build files
• npm run build for build creation
• Add to package.json import for browsers

@tshemsedinov metaschema do not work in the browser because of the metautil dependency, which in turn is tied to nodejs features.

would likely solve the issue of a separate build file from metautil for the browser

A quick fix:

-> node specific code to comments (and comment require('path') )
https://github.com/metarhia/metautil/blob/f390bfa2b4d50250d0918b92274be397457066fb/lib/strings.js#L69

-> update Extensd Error to browser Variant (note that Error is used in ./lib/async.js)
https://github.com/metarhia/metautil/blob/f390bfa2b4d50250d0918b92274be397457066fb/lib/error.js#L3

-> create ./metautil.browser.js and add all requires from metautil.js and
exclude node specific require in metautil.browser.js
https://github.com/metarhia/metautil/blob/master/lib/fs.js
https://github.com/metarhia/metautil/blob/master/lib/crypto.js
https://github.com/metarhia/metautil/blob/master/lib/http.js
https://github.com/metarhia/metautil/blob/master/lib/network.js

-> update package.json file (add field)

"browser": "metautil.browser.js",
