Switch to solveInPlace in Krylov solver component GalerkinProjection

Switched from solveLU to solveInPlace since the upper Hessenberg
system generated by the Arnoldi orthogonolization procedure may
yeild a system that is not diagonally dominate and/or contains
zeros on the diagonal. The pivoting scheme employed in solveInPlace
should help mitigate some of these issues.
