[processing] Hide redundant grid creation algorithms

Browse Source 
Condenses the duplicate grid algorithms into single algorithms
(one for line, one for polygon), taking the best bits from both
and adding tests

qgis:createconstantrasterlayer: >
Given an input raster layer an a value, this algorithm generates a new layer with the same extent and cellsize as the input one, and all cells with the specified value.
qgis:creategrid:
This algorithm creates a vector layer with a grid convering a given extent. Features can be lines or polygons, and the shape used in the grid can be rectangles, diamond or hexagons.
qgis:creategridlines:
This algorithm creates a line vector layer with a grid covering a given extent.
The size of each element in the grid is defined using a horizontal and vertical spaciong.
The size of each element in the grid is defined using a horizontal and vertical spacing.
The CRS of the output layer must be defined. The grid extent and the spacing values are supposed to be expressed in the coordinates and units of this CRS.
The CRS of the output layer must be defined. The grid extent and the spacing values must be expressed in the coordinates and units of this CRS.
qgis:creategridpolygon:
This algorithm creates a polygon vector layer with a grid covering a given extent. The grid shape can be rectangles, diamond or hexagons.
The size of each element in the grid is defined using a horizontal and vertical spacing.
The CRS of the output layer must be defined. The grid extent and the spacing values must be expressed in the coordinates and units of this CRS.
qgis:createpointsalonglines: >
This algorithms creates a points layer, with points distributed along the lines of an input vector layer. the distance between points (measured along the line) is defined as a parameter.
