VfmdLine: No explicit precomputing
Update README
VfmdByteArray: Remove unused appendBytes() method variants

Enable URLs to be output percent-encoded

Percent-encoding code is adapted from Houdini:
https://github.com/vmg/houdini/
Use renderURL() to render all URL output
Use Houdini for rendering code-blocks and code-spans
Add comments to houdini.h
Ability to render all HTML text with Houdini-style arraylookups
Render text and tag attributes using the arraylookup-based methods
Images: Bugfix: Should use constant from VfmdConstants
HtmlTextRenderer: Remove unused code
Automatic links: Split bracketed and unbracketed handling

Bracketed: Like <http://example.net>
Unbracketed: Like http://example.net

Having two separate handlers makes it easier to handle
edge cases (like an unclosed '<' followed by a link).
Automatic links: Fix handling of mailto: links
PCRE: Enable JIT
VfmdRegexp: Use PCRE in JIT mode
Paragraph: Make it compile with VFMD_NO_HTML_AWARE_END_OF_PARAGRAPH
VfmdByteArray: replaced() to replace bytes with strings
Code-span filter: Handle backslash-escaped HTML tags
