Don't use Array for associative containters?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to load table structure with column named length
2. Get uncaught exception `RangeError: invalid array length`

What version of the product are you using? On what operating system?
0.1, Mozilla Firefox 31.0, linux

I looked at the code for columns manipulation and found out that Arrays for 
columns used as associative containers, so we can replace Array with plain 
objects without any harm. Patch attached.
