Appion

I've modified insertParticlePeaks in appionlib.apParticle.py so that it would insert particle peaks without quering database first. I've also added fastInsertParticlePeaks that does direct sql insert. Here some timing stats on a small test result that shows how much performance improvement to expect:

Original version:
... inserted 3 of 3 peaks into database in 16.97 msec
... inserted 5 of 5 peaks into database in 23.74 msec

Inserting without doing a query:
... inserted 3 of 3 peaks into database in 11.74 msec
... inserted 5 of 5 peaks into database in 15.13 msec

Inserting with fastInsertParticle:Peaks:
... inserted 0 of 3 peaks into database in 1.39 msec
... inserted 0 of 5 peaks into database in 1.91 msec
