Fix alignment of selects within GridField filters
Add no results warning to GridField print view.
FIX GridField export and print actions should preserve state.
Docblock and coding conventions for GridField related classes.
FIX: Do not blindly pass input values to GridField_FormAction URL's

The length of input fields can very quickly exceed the max URI length resulting in 414 errors when printing or exporting results.

To access the input values for a specific GridField action, encapsulate this in your own Entwine instance.
Simplified travis builds (external setup scripts)

Include AllPages() form method to $allowed_actions
Merge pull request #1774 from SticksTucker/patch-1

Include AllPages() form method to $allowed_actions
FIX: _config/ directories are now correctly detected as modules (fixes #1762)

DO NOT MERGE: to be reviewed. Only i18n & Deprecation classes use
->getModules() as far as I can see. Given that the method still simply
returns an array of modulename => modulepath, I don't think it's really
an API change
Added --no-update hint to composer docs
"UploadFieldFileButtons" casting (regression from casting changes)

Caused the UploadField rows to show "[Object object]" because
it tried to pass through a PHP object to JS without string casting
(the return used to be a string).
Updated changelog, moved "statics in Page.php" to top

Its going to be a fatal error on every upgrade unless tended to,
so we need to ensure people don't overlook it in the guide.
