This adds many Efl.Text.* that are useful for manipulating the
underlying TEXTBLOCK object's propeties using efl_part.
This has been implemented as part of the "user-defined" properties of
the layout part, so that the changes on the part persist across load of
different groups.
Note that text styles have precedence over the TEXTBLOCK (Canvas.Text)
object's properties. if an edc provides a style, the properties it
manipulates as part of the "base:" string would not be affected by this
API.
In general, this helps reducing the amount of styles for objects (or
modes of the same objects) that share the same setup, but are different
in some properties (e.g. ellipsis, wrap etc).

Canvas layout: add text part "expand" property
This adds "expansion modes", which are essentially the same as min/max
hints in the edje part's 'description.text' fields.
The user can then customize his widget to different modes without being
forced to create a new edje group in the theme.
Note that there is an added check in case one of the min/max text flags
are provided from the theme. In such case, all flags from this new API
will be ignored.
This fortifies misuse where the flags are set both in theme and the API.
