Gravity Perks - Limit Submissions 1.1.19

Added conditional logic for Limit Submissions feeds so feeds can be validated conditionally upon submission. Note, conditional logic is only available in the feed if using “Field Value” rules.

Improved compatibility with Gravity Flow's User Input step.
Added new gpls_limit_field_value PHP filter.

Added gpls_rule_type_choices filter to allow filtering available rule types.
Fixed fatal error that could occur if using Limit Submissions with Nested Forms and a parent form has a submission limit that's met and a child form that has not yet met its submission limit.
Added "Update URI" to plugin header to improve security.
Fixed issue where Limit Submission rules were not bypassed when editing existing entries with Gravity Flow User Input steps.
Fixed issue where field values that are left blank in a group would cause the submissions to not be limited.
