Grunt: concatenate and compress TinyMCE

[azaozz]

Add concatenation and compression modules to Grunt and make wp-tinymce.js.gz.

[azaozz]

In 25159.patch:

• Add "grunt-contrib-compress" and "grunt-contrib-concat" modules.
• Set them to concat and gzip wp-tinymce.js.gz.

Wondering if we should remove wp-tinymce.js.gz from /src. It is unreachable as /src cannot run without SCRIPT_DEBUG = true.

[azaozz]

25159.2.patch​ also adds creation date/time and source paths for the concatenated TinyMCE parts.

[azaozz]

25159.3.patch is a refresh of 25159.2.patch.

In 25188:

Build tinymce.js.gz using grunt.

props azaozz.
see #25159.

In 25189:

Remove wp-tinymce.js.gz from develop.svn, as this is now part of the build process.

see #25159 and [25188].

Due to the banner with the current time (banner: '// Created: <%= grunt.template.today("UTC:yyyy-mm-dd HH:MM:ss Z") %>\n',), wp-tinymce.js changes every time the build process is run, and due to that, wp-tinymce.js.gz also changes.

This has lead to several sync commits to the "old" core.svn. having wp-tinymce.js.gz in them today.

Replying to TobiasBg:

This has lead to several sync commits to the "old" core.svn. having wp-tinymce.js.gz in them today.

Indeed, every changeset in ​http://core.svn.wordpress.org/trunk now has wp-tinymce.js.gz in the list of modified files.

Generally that banner is nice-to-have, non essential. Lets remove it for now. Perhaps this can be replaced with importing some ​info from package.json.

[azaozz]

Actually 25159.4.patch works quite well. Reads package.json as per the example and uses name and version for the banner.

[azaozz]

In 25200:

Remove the banner when concatenating TinyMCE so wp-tinymce.js.gz doesn't change every time the build process is run. See #25159.
