feat(*): preprocessors, custom input format and timezone become filters

close #174

BREAKING CHANGE:

Preprocessors, timezones and input format were removed from am-time-ago and all filters. Use the new `amFromUnix`,
`amUtc`, `amUtcOffset`, `amTimezone`, and `amParse` filters instead.

Examples:
* `<time am-time-ago="myDate" am-format="YYYY-MM-DD">` becomes `<time am-time-ago="myDate|amParse:'YYYY-MM-DD'">`
* `<time am-time-ago="myDate" am-preprocess="unix">` becomes `<time am-time-ago="myDate|amFromUnix">`
* `{{myDate|amCalendar:'unix'}}` becomes `{{myDate|amFromUnix|amCalendar}}`
* `{{myDate|amCalendar:null:'PDT'}}` becomes `{{myDate|amTimezone:'PDT'|amCalendar}}`

The removal of the preprocessors also affects the other positional parameters of the `amTimeAgo`:

`{{myDate|amTimeAgo:null:true:fromDate}}` becomes `{{myDate|amTimeAgo:true:fromDate}}`.

 ## 0.10.3 - 2015-09-05
 - Allow `amDateFormat` to work with custom formatted input date strings ([#162](https://github.com/urish/angular-moment/pull/162), contributed by [jblashka](https://github.com/jblashka))
 - `amAdd`, `amSubtract` - add/subtract a value from a given date ([#171](https://github.com/urish/angular-moment/pull/171), contributed by [nicholasruggeri](https://github.com/nicholasruggeri))

-### Configuration
-
-Parameter `preprocess`(e.g: `unix`, `utc`) would pre-execute before.
-
-```js
-angular.module('myapp').constant('angularMomentConfig', {
-	preprocess: 'unix', // optional
-	timezone: 'Europe/London' // optional
-});
-```
-
 ### Timeago directive
 Use am-time-ago directive to format your relative timestamps. For example:
 
 ```html
 <span am-time-ago="message.time"></span>
-<span am-time-ago="message.time" am-preprocess="unix"></span>
 ```
 
 angular-moment will dynamically update the span to indicate how much time
