DOM.normalize() not working properly in IE

[PawelMaj]

On Line 419, thisParentNode.normalize(); is called in order to combine and clean up all child nodes. On certain versions/certain settings in IE, the normalize(); function does not work correctly. It does not combine the child nodes, which in turn leads to faulty results.

For example:

1. Searching for "pm" in [email protected]
2. The child nodes could be "cs.p", "[email protected]".
3. blast.js will search for "pm" in "cs.p"
4. blast.js will search for "pm" in ""[email protected]"

Both will return no matches. The correct functionality should be:

1. Searching for "pm" in "[email protected]"
2. The child nodes should just be "[email protected]".
3. blast.js will search for "pm" in "[email protected]"
   A match is found.

I know this is mostly a bug in IE, but maybe changing the code to not use this function, and instead doing it manually might be the better choice. Another solution might be to combine all child nodes into one, before searching through them. Although this is not necessary a bug with blast, it does affect it.
