PBKDF2 added plus examples

ESLSecurity now contains a method for generating keys with PBKDF2
(password-based key derivation function 2). Two new additions to Small
Basic code examples also.
patched ESLStorage

should fix "Object reference not set to an instance of an object"
exceptions caused by my failing to change some code when I expanded the
total array amount to a max of 64. Miscellaneous changes include some
extra file format definitions in ESLFormats.xml
radix conversion expansions

added ternary conversion methods, as well as methods for multiplying
various radices (e.g. HexMultiply("FF", "FF"); )
ESLSystem patches

patched errors when using ESLSystem, and added Ping() to ESLNetworking
Merge pull request #3 from McSherry/nightly

This patch fixes issues with ESLSystem, as well as adding ESLNetworking.Ping() (measures the time taken for a web server to respond to a request, in milliseconds), the ability to convert to and from ternary, as well as methods for mathematics using various radices (e.g. HexMultiply(), OctalDivide()).
