Disentangle block "symbolic name" from title

[asmecher]

See http://forum.pkp.sfu.ca/t/ojs3-display-custom-block-name-option/29154/2.

Currently the "block name" field is used...

• As a column in the grid row
• As a symbolic name in the back-end (e.g. plugin name in plugin_settings)

It is currently limited to alphanumerics, as it's symbolic.

Suggested:

• Have the symbolic name auto-generated (using e.g. uniqid) and not presented to the user anywhere.
• Make the current "block title" field a proper title field, not limited to alphanumeric characters. Use this for the grid column, and have it display as a block title when the block is displayed.
• Keep the block title optional, in case users want a block e.g. with image-only content.

The above commits (identical but applied to different branches) allow the editing/deletion of blocks that have already been created (e.g. in OJS 2.x) with spaces in their names. The other issues listed above are not yet addressed.

I was taking a look at this plugin, and the implementation has the potential to generate unexpected conflicts, on the screenshot I created an item using the name "crossrefplugin" (as it adds an enabled = 1 to the settings, it can be used to enable plugins):
