Separate get_current_version() into functions to retrieve actual version and one to retrieve its wp-parser-since term object

* get_current_version() now returns a string of the actual version of parsed WP code (or best effort)
* Prefer ‘wp_parser_imported_wp_version’ option value as set in newer version of parser
* Add get_current_version_term() to return wp-parser-since term object for the major version of parsed WP code
* Add argument to permit get_current_version_term() to return term object for actual version
Add link to core.trac to view code source for item. props DrewAPicture

* Change “Source:” label to “Source file:”
* Add “View source...” link that points to relevant line in core.trac when appropriate
In get_current_version(), use the global wp_version instead of a hardcoded version number, unless wp_version isn't a release version. props keesiemeijer

update link
Change lingering incorrect text domains to 'wporg'
Add inline source display for functions and methods. props atimmer
More efficient implementation of get_source_code()
Add get_source_code_root_dir() which gets 'wp_parser_root_import_dir’ option value if set by parser, else ABSPATH
Add post_type_has_source_code()
Use 'wporg' as the text domain
Slight tweak to JS height comparison to ensure functions that just fit don't trigger expansion handling
Allow x scrollbar for .source-code-container and adjust heights to account for its possible display
Add extra height to collapsed state of .source-code-container to partially show the first hidden line to better indicate there is more code
Add right border to .source-code-container so it is easier to tell if code is being clipped
Change 'View source' link to 'View source code:' label with explicit links to inline source and/or WP Trac code browser
Source code is stored in post meta; parse and store it as requested if it isn't
Sanity check to ensure proper conditions exist for parsing
Add optional 'force_parse' arg to get_source_code() to force reparsing of source file
