code and ui cleanups

[dfelinto]

1. all UI parameters need to start with a captalized letter
2. created scene.blam to keep scene namespace clean
3. stripped whitespaces out
4. add two lines separation between classes
5. replaced some camelcase variables by underscore separated
6. cleaned UI code (no need for rows

I'm trying to use BLAM for a project, and for that I will need to do some changes.

I don't know if my changes will be 'mergeable' since it may be too hacky, but either way I wanted to cleanup the script a bit to understand it better.

So I thought I may as well pull request the cleaning up, in case you find it useful.
cheers

I'm suggesting some general UI cleanups

• Replacing long button names with short ones (tool-tips explain the functions adequately)
• Reduce box usage (they add clutter)
• Consistency in capitalization
• Restriction to 2.70+ tabs ("Tools" in 3D View, "Solve" in Movie Clip Editor)

Thanks!
