Update lspconfig, add indent-blanklineHEADmaster

indent-blankline is probably old because I've actually been using it for
ages, but I have a strict if-it-ain't-broke policy, so I'm not going to
update it.

lspconfig *was* broke though with nvim 0.10, so now it's fixed.

+
+IMPORTANT: If you want all the features jdtls has to offer, [nvim-jdtls](https://github.com/mfussenegger/nvim-jdtls)
+is highly recommended. If all you need is diagnostics, completion, imports, gotos and formatting and some code actions
+you can keep reading here.
+
+For manual installation you can download precompiled binaries from the
+[official downloads site](http://download.eclipse.org/jdtls/snapshots/?d)
+and ensure that the `PATH` variable contains the `bin` directory of the extracted archive.
+
+```lua
+  -- init.lua
+  require'lspconfig'.jdtls.setup{}
+```
+
+You can also pass extra custom jvm arguments with the JDTLS_JVM_ARGS environment variable as a space separated list of arguments,
+that will be converted to multiple --jvm-arg=<param> args when passed to the jdtls script. This will allow for example tweaking
+the jvm arguments or integration with external tools like lombok:
+
+```sh
+export JDTLS_JVM_ARGS="-javaagent:$HOME/.local/share/java/lombok.jar"
+```
+
+For automatic installation you can use the following unofficial installers/launchers under your own risk:
+  - [jdtls-launcher](https://github.com/eruizc-dev/jdtls-launcher) (Includes lombok support by default)
+    ```lua
+      -- init.lua
+      require'lspconfig'.jdtls.setup{ cmd = { 'jdtls' } }
+    ```
+    ]],
