[PATCH] Technologies in process of research should show up along the side of the screen

[michael]

The icons of technologies currently being researched, along with green progress overlay, could show up along the side of the screen for visual quick-reference. Mouseover/hover can show a tooltip with the pertinent information. Queued items are not to be included--only those items in progress.

Possible enhancements include:

• Include units being trained in this feature.
• Click icon to center camera and select appropriate structure.

I've implemented this for techs. I've opted not to incorporate in-training units for now, but it'd be easy enough to add that functionality if it's desired.

The button layout code is a one-off because the generic functions (in unit_commands.js) are intended for rows and would've needed a fair bit of column-specific tweaking.

I also made some graphical tweaks to the buttons in the column (specifically, the green progress bar only renders over the icon, not the button border). Again, easy to change back if it's undesirable, but I for one think it looks much better.

The 'z' attributes for the game menu and developer menu were mucked with a bit due to odd rendering issues (progress bars rendering over the menu background, et cetera).

Can you post a screenshot so we can see how it looks in action, and how it compares with Michael's mockup?
