MAINT Deprecate LDA/QDA in favor of expanded names
...
The LDA accronym for Linear Discriminant Analysis is ambiguous
because of the newly introduced Latent Dirichlet Allocation model.
We therefore deprecate the sklearn.lda.LDA and sklearn.lda.QDA
in favor of explicit names.

Simplify optimization
...
* remove L-BFGS, gradient descent finds better visualizations (although the cost is often higher)
* learning_rate is a parameter
* learning schedule:
* initialize embedding with standard deviation 1
* 100 episodes with early exaggeration
* 20 iterations with momentum 0.5
* then switch to momentum 0.8
* default learning rate is 100, reasonable range is 100-500

Replaced all BSD style licenses with "BSD 3 clause"
Not checked yet!
Removed duplicate "3 clause, 3 clause"
Removed trailing period if exists
Fixed some missed licences, still about 50 to do, but those can be automated
Think I got the last of them.
Apparently me and sed have different ideas of regex.
