Layout revamp!

[jefflunt]

What I've done is merge David's changes into master, merged those changes into a new branch layout-changes-merge, and then reverted the merge on master. The current state of things requires full testing before deployment, so I need to keep the master branch unchanged for now.

Some immediate issues:

• The layout changes break almost half of the cucumber scenarios. I plan to address this by the weekend. This is probably the most important, first issue to make sure layout hasn't also broken functionality of the app.
• Some of the color choices simply aren't comfortably readable because of low contrast between foreground and background colors.

What I like about the updates to the layout:

• The new navigation that stays on the top of the page is nice
• The "Logout" control being under the username is a good thing
• The new left-side navigation is pretty good, both from a functional and layout/positioning perspective
• Moving the add/delete controls for WorldObjects to the right side seems natural
• Abandonment of the small caps font in several places in the layout is probably a good thing from a readability standpoint
• The new table layout is more readable

Some additional changes I expect to make to the layout (just off the top of my head, after briefly looking at the new layout):

• Integrate the flash messages back into the navigation bar. From a layout and space usage standpoint, I prefer that temporary messages not modify the vertical layout of the page
• The spacing between page elements (e.g. LogBook navigation on the left and the section layout on the right)
• Getting colors in the UI to be consistent again. There are places where not everything coordinates properly, or some colors just stick out as not fitting in with the rest of the layout.
• Will probably convert the LESS to SASS for consistency at some point in the future.
• There are some general layout and spacing issues - mostly with there being more space between elements than necessary in some places. I don't want to get too-compact with the layout, because that impedes reading large tables of data. However, I think the new layout can be tightened up a bit.

Overall, I feel that the direction the new layout is taking is definitely an improvement.

I haven't yet tested the proposed fixes to issues #46 and #48. After I repair the cucumber scenarios I'll begin looking into these. As a result of how I merged, then moved, then reverted the master branch, issues #46 and #48 were closed then reopened. This was intentional.

All the tests are passing again.

The show/hiding of deleted WorldObjects in sections is broken for some reason. I opened issue #149 to address this.

One of the most common things that I found that was breaking scenarios was the use of <i> tags to display the delete/show/restore links. This really shouldn't be. If you want to use a DOM element that has a certain class to then display an icon via CSS, then a <span> or <div> element should be used instead, where appropriate. As a result I replaced these instances with the original UTF-8 characters, and cleaned up the views significantly via the addition of several helper methods.

I hope the commits are explanatory enough to cover what I changed, and why I changed it.

There's still some font and color consistency to work on, as the current, test-passing layout essentially looks the way it did before I started working on the tests.

The new layout has the latest changes from the removal of the paranoia gem, all the tests are passing and my initial testing seems to show good results at this stage.

Many of the changes that I'd like to see are going to be done later. I've decided to deploy the layout in its current state, which updates colors, resolved the Cucumber scenario issues, and some other things. Tweaks can be make later to spacing, flash messages, etc.
