add action to set the path on a file input

[Leo Arias]

Selenium handles file inputs just as textfields, but sst has a condition that forbids to use textfield_write action on a file input.
As discussed with ~cgoldberg, this function has to be extended to work with file inputs.

[Corey Goldberg (coreygoldberg)]

merged fix in trunk.

file_input.py test works on Firefox, but not with Chrome (using Chromedriver).

using:
chromedriver_linux64_14.0.836.0 (latest)
chrome 15.0 (beta)

output:

looks like a bug in chromedriver:

http://code.google.com/p/chromium/issues/detail?id=93909

confirmed on #selenium freenode that the next chromedriver release is coming next week.
