Some Chrome Frame cleanup:

1) Rearrange the chrome_frame.gyp file to:
  a) Split out most of CF into a static lib to make writing unit tests easier (not having to re-include source files).
  b) Remove most of the un-needed xulrunner-sdk includes.

2) Move all OBJECT_ENTRY_AUTO macros to chrome_tab.cc since they don't work without extra work when residing in a lib.

3) Rename npchrome_tab.dll to npchrome_frame.dll.
