Create admin Ideas controller

Some actions still need to be filled out. Admins will have more control
over the creation and editing of Idea records however.
Create empty Ideas asset files

In case Ideas will require any special functions in the admin
interface, include some new JS and CSS asset files.
Create admin Ideas helper
Create spec for admin Ideas controller and helpers
Fill in redirects after admin Idea create/update
Use Rails scaffolding to generate Admin/Ideas

  * Create an index & edit view for Ideas through the admin interface.
  * Specs are left as their default tests.

Use Rails' scaffolding to finish creating templates for managing Ideas
through the admin interface. The interface will only need the 'index'
and 'edit' views (show will be pointless and the new Idea form will be
included in the index view).
Create bootstrap-style flash messages for Admins

Use bootstrap elements to create theme-fitting flash messages for the
admin interface.
Add bootstrap-style links to admin sidebar
Create an admin-specific tag editor partial

Create a custom admin tag partial for editing Idea tags. The custom
partial has bootstrap elements applied to allow for a cleaner editing
interface on the admin side without interfering with the standard
application interface.

TODO:
  * Fix tag autocompletion in admin-specific tag partial.
Create an Idea method to return possible Idea states

Method will be used to return a list of possible values to set ideas as
through the admin interface.
Update admin layout template

  * Use bootstrap more effectively to organize layout elements in
    appropriate positions.
  * Use the admin-specific 'flash_messages' partial instead of the
    general application one.
Fill out admin Idea create/edit form

Add in editable attributes of Ideas by admins to the form partial.
Admins should be able to change all attributes but the idea's id. These
fields are available in the form partial.

TODO:
  * Fix select-input portions of the form (current, state, owner) to
    appear more bootstrappy. Currently they appear as bare HTML
    elements.
Fix '@idea' variable references in form partial

The idea to render the form partial for is named '@idea,' not
'@admin-idea.' Fix any of the 'admin-idea' references to fix the
discrepancy.
Bootstrap-ify admin Idea edit view

Make the edit view for admins changing Ideas a little prettier with
bootstrap elements to improve the layout of the page content.
Bootstrap-ify admin Idea index view header
Add reveal button/new idea partial in admin idea index

Allow admins to create Ideas from the index view but only show the
partial when they wish to view it.
Fill out table header with bootstrap styles

Make the index view for ideas prettier in the admin interface with
bootstrap CSS properties and fill out the Idea value headers.
Show individual Idea values

For each idea in the collection, show their values in the table.
Remove old positions for new/edit/destroy ideas

Since the related content is being rendered elsewhere in the template,
remove old references to links for creating/editing/deleting ideas in
the admins' Idea 'index' view.
Add an additional link break for space

Create a larger visual buffer between the idea form and the table of
all the ideas for a more aesthetically pleasing interface (move the
'save' button from being directly on top of the table).
