Add highlight groups for the signs and the lines.

Browse Source 
This allows users to customize the coloring of Syntastic's signs, and
also provides them a way to highlight the entire line using :sign's
linehl feature.  It preserves the current default behavior of using
the error and todo highlight groups if the customized ones aren't
present.  If the linehl group doesn't exist, then it's the same as not
specifying one, so no special highlighting for the line will occur.

@ -92,6 +92,30 @@ Syntastic uses the |:sign| commands to mark lines with errors and warnings in
the sign column. To enable this feature, use the |'syntastic_enable_signs'|
option.
Signs are colored using the Error and Todo syntax highlight groups by default.
If you wish to customize the colors for the signs, you can use the following
groups:
SyntasticErrorSign - For syntax errors, links to 'error' by default
SyntasticWarningSign - For syntax warnings, links to 'todo' by default
SyntasticStyleErrorSign - For style errors, links to 'SyntasticErrorSign'
by default
SyntasticStyleWarningSign - For style warnings, links to
'SyntasticWarningSign' by default
Example: >
highlight SyntasticErrorSign guifg=white guibg=red
<
To set up highlighting for the line where a sign resides, you can use the
following highlight groups:
SyntasticErrorLine
SyntasticWarningLine
SyntasticStyleErrorLine - Links to 'SyntasticErrorLine' by default
SyntasticStyleWarningLine - Links to 'SyntasticWarningLine' by default
Example: >
highlight SyntasticErrorLine guibg=#2f0000
<
