Dropdown positioning fix, build improvements and z-index fix

This release improves the dropdown positioning, npm package publication and z-index customization issues.

Changes:

• BREAKING CHANGE: We have removed z-index from the JavaScript, it is now only set in the CSS so it can be overridden in your own styles. #307
• Menu Positioning: Improve menu positioning when the input isn't the lowest element on the page. #331
• NPM package missing files: Fixed an issue where the src directory was not included in the NPM release and some other smaller build improvements. #317, #316, #315

Thanks to @iskandiar, @aldhsu, @DanielRuf for their contributions to this release!

Remove resetSelection

resetSelection is no longer needed.

Set default noMatchTemplate

Without a default noMatchTemplate then hitting backspace will not trigger the dropdown again. #53 (comment)

Fix bug in last release related to mouseup

3.5.0 introduced an update that bound to mouseup instead of mousedown. This release reverts that change and cleans out some old unused bindings.

Positioning, Event Binding and Space event selection, oh my!

This update fixes some position issues on mobile-size device screens of the menu as well as introduces some new configuration options.

• Correctly position menu on mobile devices with limited screen real estate. #177 Thank you @fynnfeldpausch!
• Use mouseup instead of mousedown for event binding. #176 Thank you again @fynnfeldpausch!
• Return mention text in lookup when lookup is a function. 3e805c5

lookup: function (item, mentionText) {
 ...
}

• Add support for selecting match when spacebar is pressed. This is disabled by default and can been enabled by setting spaceSelectsMatch to true in your config. 994fbf2 Thank you @htmltiger for the suggestion.

Thank you to everyone who contributed to this release!
