Improve structure for elements in the "new item" dialog.

[gkronber]

We should think about a better structure for "creatable" items. Especially the "Algorithms" group contains a large set of rather different algorithms (e.g. "Benchmark algorithm", "Hungarian algorithm", "BFGS", multiple variants of GAs. One idea would be to split the algorithms group based on optimization paradigms (evolutionary, trajectory-based, gradient-based, ...). The "Data-Analysis" could be split into "Regression", "Classification", "Clustering", "Time-series Prognosis".

We should probably also remove the version information from the "new item"-dialog.

Please make a treeview and a searchbox (similar to TypeSelectorDialog).

[gkronber]

Multinomial Logit Classification is assigned to an incorrect group (regression).

[gkronber]

Exceptions might occur for people with old or custom plugins using the old constructor of CreateableAttribute. I suggest to leave the old constructor (using a default priority) and marking it as obsolete?

[ascheibe]

Reviewed changes, looks good! Please have a look at r12622 and r12649 before merging into stable.

[mkommend]

r12664: Corrected ctors of CreatableAttribute.

[mkommend]

Reviewed r12622 and r12649. Though Resharper suggestions are in general advisable, I really liked the explicit usage of named parameters to strengthen the readability of the source code.

[mkommend]

This ticket must be released together with #2387.
