Fix spelling issues in solarized theme.

The bad spelling words were not shown using different colors, I realized
this when my colleagues suggested corrections on my pull requests.

They were bragging that their IDE fixes them :)

This is solution to these spelling issues.

Spelling commands:

For vim spell check help:

```
:help spell-quickstart
```

On top of a spelling word:

```
z=  : get a spelling suggestion
zg  : add good word to spell file
zw  : add wrong word to spell file
zug : remove good word from spell file
zuw : remove wrong word from spell file
```
