by guinness74: Killed another unused $success variable. Broke apart two lines over 80 chars. Removed check_url() from Form API #default_value elements because according to DrupalPractice it wasn't necessary.

by guinness74: Fixed typos in README.txt. Wrapped calls to variable_get('sendy_url', '') in check_url() for security reasons. Added check_plain() to sanitize blurb text in sendy block. Killed unused $success variable. Variables passed to watchdog() via array parameter with token replacements instead of string concatenation. Thanks to rzan for module review suggestions.

Added full stops to the end of parameter comments.

Updated documentation and code style with the help of coder module. There are no functional changes in this commit.

Added working, first version of the sendy module. (Development was previously done in a private Github repository.)
