xpectr 0.4.2

Patch for CRAN compatibility with upcoming R changes.

xpectr 0.4.1

wrapStringAddin() now wraps short strings in paste0() as well. Previously, strings that were too short to be split were not wrapped.
Adds insertExpectationsCopyEnvAddin() addin. Same as insertExpectationsAddin() but where code is evaluated in a deep copy of the parent environment. This is especially useful when testing a function that alters non-local variables and has side effects (error/warnings/messages).
Multiple functions now allow working on a deep copy of the environment (see new copy_env argument). This is useful when testing a function that alters non-local variables. It is disabled by default to save memory.
gxs_function() now allows parallelization of the expectation generation process. Requires a backend, as setup with doParallel::registerDoParallel(4). Remember to set parallel = TRUE when calling gxs_function().
strip() and strip_msg() now strips ANSI control sequences by default.
strip() and strip_msg() can now make the strings lowercase (disabled by default).
capture_side_effects() disables crayon locally before evaluating the expression (by default). Avoids ANSI control sequences in messages.
capture_parse_eval_side_effects() now has the same options as capture_side_effects().
Bug fix: "Assigned data "NULL" must be compatible with existing data."

Breaking: element_classes() only returns the first class string per element.
Adds navigateTestFileAddin() addin for opening test file from string name. E.g. when running testthat in the build window, copy the filename and line number of the failed test, e.g. test_x.R:5:, and run the addin. It will then open /tests/testthat/test_x.R at line 5.
Adds test of class attribute for errors.
Extracts error message with conditionMessage() instead of $message.
Adds indentation = 2 to generated code from initializeGXSFunctionAddin().
Bug fix: Does not check symmetry for table objects.

Adds initializeGXSFunctionAddin() addin for initializing a gxs_function() call for a selected function.
Adds initializeTestthatAddin() addin for inserting testthat::test_that() chunk.
gxs_function() gets argument extra_combinations for manually adding extra combinations of argument values. In some simple cases, this can help us avoid multiple calls to gxs_function() with different baseline values.
The Changed from baseline: comment adds the changed value when only one argument was changed. This makes it faster to see what is tested.
Tests are now properly ordered as the specified args_values.

capture_side_effects() gains argument reset_seed. Whether to reset the random state on exit (default: FALSE).
Bug fix: When generating expectations for expressions with warnings and/or messages, the random state is reset after capturing them, before evaluating the expression for its output.
Bug fix: Escapes quotation marks in error messages.
All data.frame() calls explicitly sets stringsAsFactors to ensure compatibility with r-devel.
