Add tsfmt rule to add space before parentheses of anonymous functions

Theia and VSCode format anonymous functions differently:

Theia:

    function()

VSCode:

    function ()

As people use both tools to edit the Theia code, we constantly get
spurious diffs where these are changed back and forth.  This patch adds
a tsfmt.json (picked up by the typescript language server) to align the
Theia behavior on what VSCode does.  It also adds a tslint rule and fixes
all problematic occurences.
