Merge pull request #3557 from timvandermeij/named-actions

Named actions implementation
Split files into worker and main thread pieces.
Fixes canvas alignment for small scale and scale adjustment after Cmd+0
[CRX] Fixes to view local files again

pdfHandler-local.js references the isPdfDownloadable function from
pdfHandler.js, but the function didn't expect that the responseHeaders
property was absent. Added a check to prevent a runtime error when a
local file is displayed in a frame, and show local PDF files again.

Local files are rendered on the chrome-extension:-protocol. The previous
method of getting the PDF URL was incorrect, this has been fixed as well.
Show sensible output for showText commands in the stepper.
Unprefixing CSS as current browsers support
Don't provide optional pushState parameter
