Title: Removed ignorecase default

This returns search and replace to a state where it is case sensitive.

An example of the incorrect behavior we're experiencing:

`:%s/ClassName/NewClassName` is interpreted as `:%s/ClassName/NewClassName/i`

My understanding is that `set ignoredcase` was introduced for the benefit of inline search.
With this change you would need to modify your inline search behavior:

Instead of writing:

/someinterestingclass

Use the `\c` flag ([more info](http://vim.wikia.com/wiki/Searching#Case_sensitivity)):

/someinterstingclass\c

or use the correct case:

/SomeInterestingClass

Cheers,
