[REQ] Main Toolbar icon revamp

[GoogleCodeExporter]

Update the main toolbar to use Round Textured buttons (ala Safari, Mail, et al).

Background:
In the process of designing/upgrading to Retina-quality graphics in the 1.0 
release I found it increasingly common that icons had to be completely redone 
from scratch to generate the higher resolutions required. When I was 
researching other apps and the actions their icons were depicting I found a 
trend that most apps were moving away from full colour detailed icons towards 
vector-based shapes in round-textured buttons.

See the NSTexturedRoundedBezelStyle here:

applehiguidelines/Controls/Controls.html%23//apple_ref/doc/uid/TP30000359-SW5 
and any recently released app window frames.

There seems to be an aesthetic shift towards this icon style and I would like 
to see Sequel Pro follow the trend. Constructive feedback/possible designs are 
welcome in the comments.

The nice thing about this is that the view switching would make a bit more 
sense - we can use associated items for those.

NOOOOOOOO!

I'm absolutely against going grey blob icons.
Those have always been a shame to the Apple community (which puts much pride in 
the high quality icons) and a terrible decision from an UX standpoint.

I think Apples main motivation with those was saving money, as every programmer 
can cough up such a grey blob in Illustrator in < 5 minutes, while "real" icons 
require hours and experienced designers. 

Personally I find color an integral part to make a fast decision when looking 
for something, just think about syntax highlighting in source code.
