libs/web: rewrite template engine, merge lmo library

	- template parser: merge lmo library
	- template parser: rewrite to operate on memory mapped files
	- template parser: implement proper line number reporting on syntax errors
	- template parser: process translate tags directly and bypass Lua
	- template lmo: introduce load_catalog(), change_catalog() and close_catalog()
	- template lmo: rewrite index processing to operate directly on the memory mapped file
	- template lmo: implement binary search keys, reducing the lookup complexity to O(log n)
	- po2lmo: write sorted indixes when generating *.lmo archives
	- i18n: use the template parser for translations
	- i18n: stub load(), loadc() and clear()
	- i18n: map setlanguage() to load_catalog()
