Fix typo in LRN-expression in docs

This is more consistent with krizhevsky2012, and it seems to be what the code does.
fix directory in finetune pascal example
include WindowDataLayer in data param upgrade
load transform params in window data layer
define up-to-date all-in-one model for pascal finetuning
default backend to lmdb for image conversion and mean computation

lmdb is 10-15% faster than leveldb although it takes ~1.1x the storage.
This is usually irrelevant in prefetching since both are fast enough,
but more important lmdb allows multiple, concurrent reads for training
and evaluation several models on the same data.
fix cifar10 paths so they can be run from caffe root
switch examples to lmdb (except for custom data loaders)
Changed "blas" to "openblas"

The change was made because openblas has to be linked as "-lopenblas" and not "-lblas". This caused an error when compiling.
Fixed param order of cv::Size in cv::resize
tweak test case to expose bug.
update HDF5 layer test data.
fix hdf5 data layer bug
[fix] solver indexing of output blobs was incorrect for non-singleton
outputs
Update detect.py

This generator causes an error in detect_windows because it is run twice there.
Better store it as a data structure instead.
[fix] check solver prototxt parsing
[example] fix data script paths for flickr fine-tuning
[example] add LeNet to MNIST title, fix paths to be from root
[example] re-title LeNet / MNIST heading too
[docs] update homebrew instructions for boost and boost-python split
