Undid this change since it breaks stuff. Note that the entire MatAssembly Infrastructure depends on these flags being set correctly. I just wasted hours tracking down a bug due to this change. Also note that our test system sucks since the bug was introduced a month ago.

Note also that assembled flag is MUCH more than just "values need to be communicated". The business of garray and colmap depend on this flag being set correctly.

Note also that all the other MatSetXXX still changed the flags correctly.

If you want some functionality like below that allows changing numerical values (but not nonzero locations) then introduce MatGetRowWrite() and MatRestoreRowWrite() and change MatGetRow() to MatGetRowRead(). But please don't don't underestimate side affects when you make such dramatic changes.

Now MatSetValues() does not automatically mark the matrix as unassembled
- Individual types set the assembly flag if values need to be communicated
- This is done to allow programming in the following way:
for(r = rStart; r < rEnd; ++r) {
MatGetRow()
<transform values>
MatRestoreRow()
MatSetValues()
}
