Better TypeError handling

Not passing a date format to the date filter now results in a common and expected LiquidException instead of surprising TypeError under PHP 7.1+. Other filters may also be affected.

Kudos to @PATROMO for raising the issue and providing a fix.

This release also the first one to be thoroughly tested under PHP 7.3, although earlier releases should work just as fine.

Updated whitespace control

This release comes with a much more solid implementation for the whitespace control. Kudos to @funkjedi!

Not exposing $_SERVER anymore

Fixes #114. This issue is particularly important because $_SERVER may contain sensitive data, like AWS access keys, which then can be accessed from user-provided templates.

To re-enable old unsafe behavior, use:

Liquid::set('EXPOSE_SERVER', true);

Content ticks

#113: Content ticks allow us to track the rendering cost at runtime, abort it or do something else if a template takes too much time to render. (Kudos to @timglabisch!)

Bugfix release

• Filterbank shall now ignore use of __construct as a filter (by @PATROMO)

Whitespace control for tags

• Whitespace control implemented for tags (see #109).
• Strings now have a 'size' property, for a number of characters.

Bugfix release

• Now we return null for missing properties, like we do for missing keys for arrays. (#101)

Paginate tag gets updated

• Paginate tag shall now respect request parameters.
• It is now possible to set a custom query param for the paginate tag.
• Page number will now never go overboard.

Major thanks to @edwardoka and @asacarter.

Bugfix release

• TagPaginate shall not pollute the global scope, but work in own scope. (Thanks @edwardoka and @asacarter)
• TagPaginate errors if no collection present instead of vague warning.

Bugfix release

Now a capture tag will save a variable in the global context. (Fixes #90)
