beta 1

Beta 1 should be a rather stable release. I intend to a set of (experimental) reflective syntaxes before release, like getting the type of a field, the field names of a struct, and unsafe accesses to structs with strings instead of literal field names. Excluding those, this beta is feature complete.

Changelog:

• Adds add/remove changers for fields
• Adds dynamic fields, fields that always evaluate their expression when retrieved, rather than evaluating once on creation. These cannot be set manually after creation.
• Fixes a few bugs with changers
• Adds automated test support
• Adds a struct copy expression to get deep copies of a struct.
