New plugin manager half-implemented. Most of the UI/frontend code is done. Moved sql_parse.php to /includes/ to allow use after installation - TODO: check installer, etc. for breakage

This method is API- and format-compatible with old plugins. The change is being * made because we believe this will provide greater flexibility within plugin files. * * Plugin files can contain one or more specially formatted comment blocks with metadata, language strings, and installation or * upgrade SQL schemas. For this to work, plugins need to define their version numbers in an Enano-readable and standardized * format, and we think the best way to do this is with JSON. It is important that plugins define both the current version and * a list of all past versions, and then have upgrade sections telling which version they go from and which one they go to. * * The format for the special comment blocks is: <code> /**!blocktype( param1 = "value1" [ param2 = "value2" ... ] )** ... block content ... **!* / (remove that last space) </code> * The format inside blocks varies. Metadata and language strings will be in JSON; installation and upgrade schemas will be in * SQL. You can include an external file into a block using the following syntax inside of a block: <code> !include "path/to/file" </code> * The file will always be relative to the Enano root. So if your plugin has a language file in ENANO_ROOT/plugins/fooplugin/, * you would use "plugins/fooplugin/language.json". * * The format for plugin metadata is as follows: <code> /**!info** { "Plugin Name" : "Foo plugin", "Plugin URI" : "http://fooplugin.enanocms.org/", "Description" : "Some short descriptive text", "Author" : "John Doe", "Version" : "0.1", "Author URI" : "http://yourdomain.com/", "Version list" : [ "0.1-alpha1", "0.1-alpha2", "0.1-beta1", "0.1" ] } **!* / </code> * This is the format for language data: <code> /**!language** { eng: { categories: [ 'meta', 'foo', 'bar' ], strings: { meta: { foo: "Foo strings", bar: "Bar strings" }, foo: { string_name: "string value", string_name_2: "string value 2" } } } } **!* / (once more, remove the space in there) </code> * Here is the format for installation schemas: <code> /**!install** CREATE TABLE {{TABLE_PREFIX}}foo_table( ... ) **!* / </code> * And finally, the format for upgrade schemas: <code> /**!upgrade from = "0.1-alpha1" to = "0.1-alpha2" ** **!* / </code> * Remember that upgrades will always be done incrementally, so if the user is upgrading 0.1-alpha2 to 0.1, Enano's plugin * engine will run the 0.1-alpha2 to 0.1-beta1 upgrader, then the 0.1-beta1 to 0.1 upgrader, going by the versions listed in * the example metadata block above. * * All of this information is effective as of Enano 1.1.4. */// Plugin manager "2.0"function page_Admin_PluginManager(){ global $db, $session, $paths, $template, $plugins; // Common objects global $lang; if ( $session->auth_level < USER_LEVEL_ADMIN || $session->user_level < USER_LEVEL_ADMIN ) { $login_link = makeUrlNS('Special', 'Login/' . $paths->nslist['Special'] .
