Improve support for multivalue (array) field names #10
Description
There needs to be support for multidimensional arrays. Maybe get rid of &array= and auto-detect arrays directly in FFP?
Examples:
[[!field? &type=`text` &name=`color[a]` ]]
[[!field? &type=`text` &name=`test[a][1001]` ]]
[[!field? &type=`text` &name=`something[abc][xyz]` ]]
[[!field? &name=`favorite[color]` &type=`checkbox` &options=`Blue||Red||Yellow`]]
[[!field? &name=`color[]` &type=`checkbox` &options=`Blue||Red||Yellow`]]
