sort indexes & types, filter indices, line up aliases

Hello, 
this request contains 3 commits:
1. Sort indexes and types - is pretty obvious
2. Filter indices - additional edit box in browser tab. If you type text and hit enter, list of indices below will be filtered according to words you typed.
3. Line up aliases - change in overview tab - aliases are lined up in table, eg. if all indices have one alias, in table will be only one row.
