Closes #819

• Add abs filter
• Add indent filter
• Deprecate get_json_pointer in favour of dotted_pointer, a faster alternative
• Always canonicalize glob paths passed to Tera to workaround a globwalk bug
• Handle apostrophes in title case filter

• Force chrono dep to be 0.4.20 minimum
• Better support for parenthesis in expression

• Add a feature just for the urlencode builtin
• Fix bug in slice filter if start >= end
• Allow supplying a timezone to a timestamp for the date filter

• Add default parameter to get filter
• Tera::extend now also copies over function
• Remove the new Context-local Tera function support, it was an accidental breaking change and will be added in v2 in some ways instead

• Ensure Context stays valid in Sync+Send, fixing an issue introduced in 1.13. 1.113 will be yanked.

• Add default parameter to get filter
• Tera::extend now also copies over function
• Add Context-local Tera functions

• Remove unused feature of chrono
• Remove unwanted bloat in crate from accidental WASM files

• Add spaceless filter from Django

• Allow iterating on strings with for

• Add Tera::get_template_names

• Add Context::remove

• Add linebreaksbr filter from Django
• Allow dots in context object key names

• Fix parsing of filter arguments separated by whitespaces

• Allow rendering to std::io::Write
• Follow symlinks in glob
• Allow including lists of templates
• Comment tags can now use whitespace control

• Fix date filter sometimes panicking with some format input

• Allow multiline function kwargs with trailing comma
• Add Context::try_insert

• Add the concept of safe functions and filters
• Allow negative index on slice filter

• Add Context::get and Context::contains_key

• Fix raw tag swallowing all whitespace at beginning and end
• Make batch template sources generic

• Add a urlencode_strict filter
• Add more array literals feature in templates
• Make filter filter value argument optional

• Add trim_start, trim_end, trim_start_matches and trim_end_matches filters
• Allow blocks in filter sections

• Add Tera::render_str, like Tera::one_off but can use an existing Tera instance

• Length filter now errors for things other than array, objects and strings. The fact that it was returning 0 before for other types was something that should have been fixed before 1.0 but got forgotten and was considered a bug.

• Fix filter sections not keeping whitespaces
• The filesizeformat filter now takes a usize instead of a i64: no changes to behaviour

Breaking changes

• Now requires Rust 1.34
• Removed error-chain errors and added rich Error enum instead
• Filter, Tester and Function are now traits and now take borrowed values instead of owned
• Updated for 2018 edition
• Require macros import to be at the top of the files along with extends as it is fairly cheap and the code already only really look there.
• Enforce spacing in tags at the parser, before ifsomething was considered ok
• Pluralize filter now uses singular and plural arguments instead of suffix
• Add a test for checking whether a variable is an object
• Escaping now happens before inserting the final result of an expression: no need anymore to add | safe everywhere, only at the last position
• Remove safe argument of the urlencode filter, / is still escaped by default
• The compile_templates! macro has been removed

• Add nth filter to get the nth value in an array
• You can now use glob patterns in Tera::new
• default filter now works on Null values
• Literal numbers in template overflowing i64/f64 will now be an error instead of panicking
