Super-review request for patch for bug 346035

[Andris Pavenis]

Could it possible to get super-review for patch for bug report?

https://bugzilla.mozilla.org/show_bug.cgi?id=364035

Who could be possible super-reviewer?

Short summary:

patch modifies spell-check manager to add a possibility of external
spell-check engines from Mozilla programs. When patch is applied,
extension may register external spell-check engine using
nsICategoryManager interface (one category reserved for this purpose).

Tested with using both HunSpell and 1 external spell-checker from
extension on Linux x86 and x86_64. Some tests done also for WIN32
(unfortunately I didn't yet have extension with external spell-check
engine ready for WIN32).
