2.11.0: Filenames in errors

• Merged PR #54: Ensure filenames in errors reflect source files - @thekid

2.10.1: URI loading fixes

• Fixed throw expressions with variables, e.g. () ==> throw $e;.
  (@thekid)
• Fixed URI loading for CompilingClassLoader - this way, loading
  classes via URIs works, and thus e.g. xp test path/to/Test.php.

• Merged PR #42: Raise errors when members are redeclared - @thekid

2.6.2: Dynamic members fix

• Fixed issue with dynamic instance references not being emitted
  correctly, e.g. $value->{$field->get()};, see
  http://php.net/manual/en/functions.variable-functions.php
  (@thekid)

2.6.1: String parsing fix

• Fixed issue #41: String parsing of escapes broken - @thekid

• Implemented support unicode escape sequences in PHP 5.6, see #38
  (@thekid)
• Fixed issue #39: Syntax error for parameters called "function"
  (@thekid)
• Dropped confusing way of compiling multiple sources using -b to
  strip bases. New way is to pass multiple directories directly, e.g.
  $ xp compile -o dist src/main/php/ src/test/php
  (@thekid)
• Fixed compiling to a directory when the source path was not inside
  the current directory.
  (@thekid)

2.5.1: Line number fixes

• Ensured line number is always present for type members. Previously,
  this was 0, leading to output formatting errors
  (@thekid)
• Made some minor performance improvements by reusing nodes in two
  cases - return statements and assignments
