cf. commit SHA-1: 50ecd12ce71a44717f8ec223a2fa225887ccff6d * w2layout fixes:

- there is no object attribute called 'resizabled' - it's called 'resizable' (typo 2x?)

- the panel name itself ('main', ...) is never a valid jQuery selector, there's the constructed id `pname` for that (coding mistake?)

- obj.resizable is checked everywhere as being truthy/falsy except in one place where it is explicitly checked against `true` using `===`: this check has been brought in line with all the others.
cf. commit SHA-1: 9887059b81130195146837b24341ed94c49227b2:

* add the 'load dynamic content' code from layout example 4 to layout examples 8, 9 & 10 (layout with tabs, layout with toolbar, layout with titles) so that we can observe panel overflow behaviour (previously, overflow was applied to the entire panel, i.e. including the title, toolbar and tab-bar! This has been fixed in commit SHA-1: 33202a80a2f47d930af3cb317a8bcb55121c5675)
gitignore the `npm install` directories
